text: In this study, the design, additive manufacturing and experimental
as well as simulation investigation of mechanical and thermal properties of cellular
solids are addressed. For this, two cellular solids having nested and non-nested
structures are designed and additively manufactured via laser powder bed fusion.
The primary objective is to design cellular solids which absorb a significant
amount of energy upon impact loading without transmitting a high amount of stress
into the cellular solids. Therefore, compression testing of the two cellular solids
is performed. The nested and non-nested cellular solids show similar energy absorption
properties; however, the nested cellular solid transmits a lower amount of stress
in the cellular structure compared to the non-nested cellular solid. The experimentally
measured strain (by DIC) in the interior region of the nested cellular solid is
lower despite a higher value of externally imposed compressive strain. The second
objective of this study is to determine the thermal insulation properties of cellular
solids. For measuring the thermal insulation properties, the samples are placed
on a hot plate; and the surface temperature distribution is measured by an infrared
camera. The thermal insulating performance of both cellular types is sufficient
for temperatures exceeding 100 °C. However, the thermal insulating performance
of a non-nested cellular solid is slightly better than that of the nested cellular
solid. Additional thermal simulations predict a relatively higher temperature
distribution on the cellular solid surfaces compared to experimental results.
The simulated residual stress shows a similar distribution for both types, but
the magnitude of residual stress is different for the cellular solids upon cooling
from different temperatures of the hot plate.

text: The additive manufacturing (AM) of innovative lattice structures with
unique mechanical properties has received widespread attention due to the capability
of AM processes to fabricate freeform and intricate structures. The most common
way to characterize the additively manufactured lattice structures is via the
uniaxial compression test. However, although there are many applications for which
lattice structures are designed for bending (e.g., sandwich panels cores and some
medical implants), limited attention has been paid toward investigating the flexural
behavior of metallic AM lattice structures with tunable internal architectures.
The purpose of this study was to experimentally investigate the flexural behavior
of AM Ti-6Al-4V lattice structures with graded density and hybrid Poisson’s ratio
(PR). Four configurations of lattice structure beams with positive, negative,
hybrid PR, and a novel hybrid PR with graded density were manufactured via the
laser powder bed fusion (LPBF) AM process and tested under four-point bending.
The manufacturability, microstructure, micro-hardness, and flexural properties
of the lattices were evaluated. During the bending tests, different failure mechanisms
were observed, which were highly dependent on the type of lattice geometry. The
best response in terms of absorbed energy was obtained for the functionally graded
hybrid PR (FGHPR) structure. Both the FGHPR and hybrid PR (HPR) structured showed
a 78.7% and 62.9% increase in the absorbed energy, respectively, compared to the
positive PR (PPR) structure. This highlights the great potential for FGHPR lattices
to be used in protective devices, load-bearing medical implants, and energy-absorbing
applications.

text: In this study, an innovative friction model is used to improve the quality
of clinching process simulations. Consequently, the future over dimensioning can
be reduced. Furthermore, the improved prediction quality of the joining process
simulation leads to an improvement in the simulation of load-bearing capacity
as well. In this way, the entire sampling process can be performed virtually without
any experimental investigations. This will contribute to the advancement of lightweight
construction in the automotive industry. In this work, the frictional behavior
is studied in dependence on the local joining process parameters. As a reference
for the numerical investigations, clinch joints by means of a die with fixed geometry
are joined. Additionally, a hardness mapping is performed on the microsection
of the clinch joints. It shows the local strain hardening, which correlates with
the forming degree in the simulation. Based on the occurring contacts and the
local joining process parameters in the joining process simulation, the test matrix
for the experimental friction tests is defined. The friction tests are carried
out on a compression-torsion-tribometer. This type of tribometer is able to apply
high interface pressures above the initial yield stress due to the specimen encapsulation.
Besides, the pure joining part contact, the contact between the joining part and
joining tool can be tested as well. The experimental test setup offers the possibility
to evaluate the influences of temperature, relative velocity, interface pressure,
and frictional stroke independently. Based on the results of the experimental
friction tests, a friction model is created. The resulting friction model is integrated
into the numerical joining process simulation via a subroutine. To validate the
quality of the new friction modeling, the results of simulations are compared
with the experiments in terms of load-stroke diagrams, joint geometry, and hardness
mappings on the microsection.

text: Clinching as a mechanical joining process has become established
in many areas of car body. In order to predict relevant properties of clinched
joints and to ensure the reliability of the process, it is numerically simulated
during the product development process. The prediction accuracy of the simulated
process depends on the implemented friction model. Therefore, a new method for
determining friction coefficients in sheet metal materials was developed and tested.
The aim of this study is the numerical investigation of this experimental method
by means of FE simulation. The experimental setup is modelled in a 3D numerical
simulation taking into account the process parameters varying in the experiment,
such as geometric properties, contact pressure and contact velocity. Furthermore,
the contact description of the model is calibrated via the experimentally determined
friction coefficients according to clinch-relevant parameter space. It is shown
that the assumptions made in the determination of the experimental data in preliminary
work are valid. In addition, it is investigated to what extent the standard Coulomb
friction model in the FEM can reproduce the results of the experimental method.

text: "Abstract\r\n This paper presents
the characterization of the microstructure evolution during flow forming of austenitic
stainless steel AISI 304L. Due to plastic deformation of metastable austenitic
steel, phase transformation from γ-austenite into α’-martensite occurs. This is
initiated by the formation of shear bands as product of the external stresses.
By means of coupled microscopic and micromagnetic investigations, a characterization
of the microstructure was carried out. In particular, this study shows the distribution
of the strain-induced α’-martensite and its influence on material properties like
hardness at different depths. The microstructural analyses by means of electron
backscattered diffraction (EBSD) technique, evidence a higher amount of α’-martensite
(ca. 23 %) close to the outer specimen surface, where the plastic deformation
and the direct contact with the forming tool take place. In the middle area (ca.
1.5 mm depth from the outer surface), the portion of transformed α’-martensite
drops to 7 % and in the inner surface to 2 %. These results are well correlated
with microhardness and micromagnetic measurements at different depths. EBSD and
atomic force microscopy (AFM) were used to make a detailed characterization of
the topography and degree of deformation of the shear bands. Likewise, the mechanisms
of nucleation of α’-martensite were discussed. This research contributes to the
development of micromagnetic sensors to monitor the evolution of properties during
flow forming. This makes them more suitable for closed-loop property control,
which offers possibilities for an application-oriented and more efficient production."

text: The production of complex multi-functional, high-strength parts is
becoming increasingly important in the industry. Especially with small batch size,
the incremental flow forming processes can be advantageous. The production of
parts with complex geometry and locally graded material properties currently depicts
a great challenge in the flow forming process. At this point, the usage of closed-loop
control for the shape and properties could be a feasible new solution. The overall
aim in this project is to establish an intelligent closed-loop control system
for the wall thickness as well as the α’-martensite content of AISI 304L-workpieces
in a flow forming process. To reach this goal, a novel sensor concept for online
measurements of the wall thickness reduction and the martensite content during
forming process is proposed. It includes the setup of a modified flow forming
machine and the integration of the sensor system in the machine control. Additionally,
a simulation model for the flow forming process is presented which describes the
forming process with regard to the plastic workpiece deformation, the induced
α’-martensite fraction, and the sensor behavior. This model was used for designing
a closed-loop process control of the wall thickness reduction that was subsequently
realized at the real plant including online measured feedback from the sensor
system.

text: The further development of in-mold-assembly (IMA) technologies for
structural hybrid components is of great importance for increasing the economic
efficiency and thus the application potential. This paper presents an innovative
IMA process concept for the manufacturing of bending loaded hybrid components
consisting of two outer metal belts and an inner core structure made of glass
mat reinforced thermoplastic (GMT). In this process, the core structure, which
is provided with stiffening ribs and functional elements, is formed and joined
to two metal belts in one single step. For experimental validation of the concept,
the development of a prototypic molding tool and the manufacturing of hybrid beams
including process parameters are described. Three-point bending tests and optical
measurement technologies are used to characterize the failure behavior and mechanical
properties of the produced hybrid beams. It was found that the innovative IMA
process enables the manufacturing of hybrid components with high energy absorption
and low weight in one step. The mass-specific energy absorption is increased by
693 % compared to pure GMT beams.

text: Requirement changes and cascading effects of change propagation are
major sources of inefficiencies in product development and increase the risk of
project failure. Proactive change management of requirement changes yields the
potential to handle such changes efficiently. A systematic approach is required
for proactive change management to assess and reduce the risk of a requirement
change with appropriate effort in industrial application. Within the paper at
hand, a novel method for Proactive Management of Requirement Changes (ProMaRC)
is presented. It is developed in close collaboration with industry experts and
evaluated based on workshops, pilot users’ feedback, three industrial case studies
from the automotive industry and five development projects from research. To limit
the application effort, an automated approach for dependency analysis based on
the machine learning technique BERT and semi-automated assessment of change likelihood
and impact using a modified PageRank algorithm is developed. Applying the method,
the risks of requirement changes are assessed systematically and reduced by means
of proactive change measures. Evaluation shows high performance of dependency
analysis and confirms the applicability and usefulness of the method. This contribution
opens up the research space of proactive risk management for requirement changes
which is currently almost unexploited. It enables more efficient product development.

text: Inspired by plant grafting, grafted vortex beams can be formed through grafting
two or more helical phase profiles of optical vortex beams. Recently, grafted
perfect vortex beams (GPVBs) have attracted much attention due to their unique
optical properties and potential applications. However, the current method to
generate and manipulate GPVBs requires a complex and bulky optical system, hindering
further investigation and limiting its practical applications. Here, a compact
metasurface approach for generating and manipulating GPVBs in multiple channels
is proposed and demonstrated, which eliminates the need for such a complex optical
setup. A single metasurface is utilized to realize various superpositions of GPVBs
with different combinations of topological charges in four channels, leading to
asymmetric singularity distributions. The positions of singularities in the superimposed
beam can be further modulated by introducing an initial phase difference in the
metasurface design. The work demonstrates a compact metasurface platform that
performs a sophisticated optical task that is very challenging with conventional
optics, opening opportunities for the investigation and applications of GPVBs
in a wide range of emerging application areas, such as singular optics and quantum
science.

text: Subwavelength dielectric resonators assembled into metasurfaces have become
a versatile tool for miniaturizing optical components approaching the nanoscale.
An important class of metasurface functionalities is associated with asymmetry
in both the generation and transmission of light with respect to reversals of
the positions of emitters and receivers. The nonlinear light–matter interaction
in metasurfaces offers a promising pathway towards miniaturization of the asymmetric
control of light. Here we demonstrate asymmetric parametric generation of light
in nonlinear metasurfaces. We assemble dissimilar nonlinear dielectric resonators
into translucent metasurfaces that produce images in the visible spectral range
on being illuminated by infrared radiation. By design, the metasurfaces produce
different and completely independent images for the reversed direction of illumination,
that is, when the positions of the infrared emitter and the visible light receiver
are exchanged. Nonlinearity-enabled asymmetric control of light by subwavelength
resonators paves the way towards novel nanophotonic components via dense integration
of large quantities of nonlinear resonators into compact metasurface designs.

text: The free exciton transition (near-band-edge emission, NBE) of ZnO at ≈388
nm can be strongly enhanced and even stimulated by an underlying photonic structure.
1D Photonic crystals, so-called distributed Bragg reflectors, are utilized to
suppress the deep-level emission of ZnO (DLE, ≈500–530 nm). The reflector stacks
are fabricated in a layer-by-layer procedure by wet-chemical synthesis. They consist
of low-ε porous SiO2 layers and high-ε TiO2 layers. Varying the thickness of the
SiO2 layers allows tuning the optical bandgap in a wide range between ≈420 and
800 nm. A ZnO layer is deposited on top of the reflector stacks by sol–gel synthesis.
The spontaneous photoluminescence (PL) emission of the ZnO film is modulated by
the photonic structure. When the optical bandgap of the reflector is in resonance
with the deep-level emission of ZnO (DLE, ≈500–530 nm), then this defect-related
emission mode is suppressed. Strong NBE emission is observed even when the ZnO
layer does not show any NBE emission (due to low crystallinity) in the absence
of the photonic structure. With this cost-efficient synthesis method, emitters
for, e.g., luminescent gas sensors can be fabricated.
