text: 'Abstract. This study presents intrinsic lubrication as a novel approach
to deep drawing processes, using additively manufactured, lubricant-permeable
tools to minimize lubricant consumption and improve efficiency. Two systems were
evaluated: a passive system based on capillary action and gravity, and an active
system using pumped delivery for precise, on-demand application. Experimental
tests were conducted on micro-bores (0.2-0.5 mm) to demonstrate their suitability
for lubricant transport. Smaller bores have excellent capillary action but are
prone to clogging, while larger bores offer higher permeability. The passive system
is resource-efficient but requires adjustments to counteract gravitational asymmetry.
The active system provides consistent lubricant distribution but is more complex.
These findings provide a basis for optimizing intrinsic lubrication systems.'

text: "This paper deals with the implementation and results of the application of
a multi-stage traffic light control system which includes a simulation-based traffic
estimation and model predictive control.\r\nThe traffic light control system incorporates
a fuzzy system for traffic light phase preselection, followed by a model predictive
control to optimise phase combinations and switching times. Predefined phases
are selected without restrictions in the order according to a multi-objective
optimisation to adapt to the traffic as freely as possible. Initially, the system
is tested in simulations and compared with existing methods and analysed afterwards
for its effectiveness in a prototype commissioning in field tests. Results indicate
high potentials for reducing emissions and waiting times, highlighting the system's
value. However, further refinement is necessary for standard implementation. This
comprehensive approach demonstrates advancements in traffic management technology,
showcasing the potential for enhancing urban mobility and reducing environmental
impact."

text: "One of the most important strategies for reducing CO2 emissions in the mobility
sector is lightweight construction. In particular, the car body offers several
opportunities for weight reduction. Multi-material designs are increasingly being
applied to select the most suitable material for the respective load and ultimately
achieve synergy effects. For example, aluminium castings are used at the nodes
of a spaceframe body. Subsequently, these are joined with profiles to form the
bodyshell. To join different materials mechanical joining techniques, such as
semi-tubular self-piercing riveting, are deployed. According to the current state
of the art, cracks occur in the aluminium castings during the mechanical joining
process as a result of the high degree of deformation. Although the aluminium
casting alloys of the AlSi-system exhibit low ductility, these alloys reveal excellent
castability. In particular, the ability to cast thin structural parts is enabled
by the low liquidus point of the near eutectic aluminium casting alloys.\r\nThis
study addresses the mechanical joining properties of the near eutectic aluminium
casting alloy AlSi12, depending on different microstructures. These are achieved
by annealing processes and modifying agents. Through an adapted heat treatment,
the previously lamellar morphology can be transformed into a globular morphology,
which leads to increased ductility and prevents the formation of cracks during
the self-piercing riveting (SPR). The joinability is investigated using different
die geometries, whereas the joint formation is analysed regarding crack initiation.
To evaluate the increased ductility, microstructural and mechanical tests are
performed and finally, a microstructure-joinability correlation is established."

text: The constantly increasing demand for climate protection and resource conservation
requires innovative and versatile joining processes that improve adaptability
to the joining task and robustness to enable flexible manufacturing on a production
line. Therefore, the versatile SPR (V-SPR) and tumbling SPR (T-SPR) were developed.
Using the example of a mixed material combination HCT590X+Z (t0 = 1.0 mm) / EN
AW-6014 T4 (t0 = 2.0 mm), these processes were examined and compared with regard
to the binding mechanisms form closure and force closure using micrographs, non-destructive
resistance measurements and destructive torsion tests. For this purpose, a new
sample geometry was defined, and the methods were adapted to the SPR process variants.

text: The accurate prediction of crack initiation and propagation is essential for
assessing the structural integrity of mechanically joined components and other
complex assemblies. To overcome the limitations of existing finite element tools,
a modular Python framework has been developed to automate three-dimensional crack
growth simulations. The program combines geometric reconstruction, adaptive remeshing,
and the numerical evaluation of fracture mechanics parameters within a single,
fully automated workflow. The framework builds on open-source components and remains
solver-independent, enabling straightforward integration with commercial or research
finite element codes. A dedicated sequence of modules performs all required steps,
from mesh separation and crack insertion to local submodeling, stress and displacement
mapping, and iterative crack-front update, without manual interaction. The methodology
was verified using a mini-compact tension (Mini-CT) specimen as a benchmark case.
The numerical results demonstrate the accurate reproduction of stress intensity
factors and energy release rates while achieving high computational efficiency
through localized refinement. The developed approach provides a robust basis for
crack growth simulations of geometrically complex or residual stress-affected
structures. Its high degree of automation and flexibility makes it particularly
suited for analyzing cracks in clinched and riveted joints, supporting the predictive
design and durability assessment of joined lightweight structures.

text: Abstract. In the development of advanced lightweight automotive solutions,
self-piercing riveting (SPR) offers the possibility of joining multi-material
structures to fulfil a wide variety of requirements. With regard to the entire
process chain, production-related pre-deformations of the parts to be joined can
influence the geometric shape and load capacity of SPR joints. Various studies
have investigated the influence of pre-stretched sheet materials, in the sense
of pre-drawing processes, on the formation of SPR joints. The impact of pre-stretching
sheet metals on the formation of their geometrical characteristics and the shear-tensile
strength of SPR processes was observed [1]. Pre-rolled semi-finished products
are also joined together in mixed material automotive structures, e.g. tailor
rolled blanks. This work aims to investigate the influence of pre-rolled joining
parts on the geometric formation and load-carrying capacity of SPR joints. For
this purpose, sheets of metal are cold-formed using a rolling process to induce
a defined strain-hardening state in the material and then joined in various combinations.
As the degree of deformation increases, the rolling of samples can lead to minimal
accumulation of damage in the sheet materials, which can influence the joint behaviour.
The rolling process, as well as the subsequent joining process, are also investigated
by FEM. The influence of pre-rolled semi-finished products on the strength of
the SPR joints is investigated.

text: Abstract. Saving emissions and a circular economy are key aspects
of sustainable production and compliance global climate change targets. Friction-induced
solid-state recycling of aluminum scrap to production endless semi-finished products.
Scrap is fed into a continuously rotating wheel. This requires less energy compared
to heat-based recycling processes. Different sizes, shapes and surfaces of chips
can be used as starting material in the process. The influence of this has been
shown in past publications. A native oxide layer is a fixed component of aluminum
surface. This layer is broken up during the forming process, allowing the aluminum
to bond. In addition to the geometry, the surface finishes and the thickness of
the oxide layer are therefore also important input variables in friction-induced
solid-state recycling. The oxide layers on the chips were determined for the investigation.
In addition, different layer thicknesses were produced to survey their influence.
The resulting semi-finished products were evaluated on the basis of their tensile
strength and microstructure. The main result of the investigations is the fact
that semi-finished products made from chips with thicker oxide layers tend to
be more brittle. In addition, thick oxide layers cause microstructural and surface
defects.

text: "Die Extrusion stellt das mengenmäßig dominante Verarbeitungsverfahren für
thermoplastische Kunststoffe dar. Daher gibt es starke Bestrebungen in diesem
Bereich hin zu einer höheren Wirtschaftlichkeit, welche beispielsweise durch höheren
Massedurchsatz bei gleichbleibender Maschinengröße erreicht werden kann, oder
aber auch im Hinblick auf eine Kreislaufwirtschaft die Bestrebung hin zu einer
materialschonenden Verarbeitung. Beide Bestrebungen erfordern spezielle Schneckenkonzepte.
Hierunter fallenWave- Schnecken, welche in beiden Bereichen ein vorteilhaftes
Prozessverhalten aufzeigen sollen. Die Auslegung von Wave-Schnecken erfordert
jedoch ein stärkeres Verständnis über das geometrieabhängige Prozessverhalten
in der Extrusion. \r\nIm Rahmen der Dissertation werden zwei Themengebiete angegangen.
Das erste Thema ist die Herleitung einer Methode zur Charakterisierung des Abbauverhaltens
von Thermoplasten sowie die Nutzung der Charakterisierung als Vorhersagemodell.
Das zweite Thema behandelt die Auslegung von Wave-Schnecken basierend auf numerischen
Simulationen samt Validierung anhand von sieben Energy-Transfer-Schnecken im Vergleich
zu drei konventionellen Schnecken. Hierbei werden unter anderem der Materialabbau,
die thermische und die stoffliche Homogenität betrachtet, um ein umfassendes Bild
über das Prozessverhalten der Schnecken zu schaffen. Die vorgestellten Untersuchungen
dienen schlussendlich zu einer Bestätigung des vorteilhaften Prozessverhaltens
von Wave-Schnecken."

text: "The extrusion process is the dominant processing method for thermoplastics
in terms of quantity. For this reason, there are strong efforts in this area towards
greater economic efficiency, which can be achieved, for example, through higher
mass throughput with the same machine size, or, with regard to a circular economy,
towards material-preserving processing. Both endeavours require special screw
concepts. These include wave screws, which should demonstrate advantageous process
behaviour in both areas. However, the design of wave screws requires a better
understanding of the geometry-dependent process behaviour in extrusion. \r\nTwo
topics are addressed in the dissertation. The first topic is the derivation of
a method to characterise the degradation behaviour of thermoplastics and the use
of the characterisation as a predictive model. The second topic deals with the
design of wave screws based on numerical simulations including validation using
seven energy transfer screws in comparison to three conventional screws. Among
other things, the material degradation, the thermal and the material homogeneity
are considered in order to create a comprehensive picture of the process behaviour
of the screws. The presented investigations ultimately serve to confirm the advantageous
process behaviour of wave screws."

text: In order to standardize spray flame synthesis (SFS) studies, intensive work
has been done in recent years on the design of burner types. Thus, in 2019, the
so-called SpraySyn1 burner was introduced (SS1), which was subsequently characterized
in numerical and experimental studies. Based on this research, a modification
of the nozzle design was proposed, which has now been considered in the successor
model, SpraySyn2 (SS2). As little is known about the effect of the nozzle adaptation
on the particle formation, we operated both burners under identical operating
conditions to produce maghemite. The final powder comparison showed that SS2 yielded
considerable higher specific surface areas (associated with smaller primary particle
sizes), lower polydispersity, and higher phase purity. To obtain further information
on the size distributions of aggregates and agglomerates generated by SS2, aerosol
samples were extracted by hole in a tube (HIAT) sampling and characterized by
scanning mobility particle sizing (SMPS). Samples were extracted along the centerline
at different heights above the burner (HAB) above the visible flame tip (>7 cm),
and quenching experiments were performed to extract the aerosol samples at different
dilution rates. Thereby, it was demonstrated that performing detailed quenching
experiments is crucial for obtaining representative HIAT-SMPS data. In particular,
agglomerates/aggregate sizes were overestimated by up to ~70 % if samples were
not sufficiently diluted. If sufficient dilution was applied, distribution widths
and mean particle mobility diameters were determined with high accuracy (sample
standard derivation <5 %). Our data suggested the evolution of primary particle
sizes was mostly completed <7 cm HAB and it was shown aggregates/agglomerates
present above the visible flame were compact in structure (non- fractal). The
mean diameter of the particle ensemble grew along the centerline from 6.9 nm (7
cm) to 11.4 nm (15 cm), while distribution widths grew from 1.42 to 1.52.

text: AbstractPolycarbonate (PC) is an amorphous
polymer that is an extremely robust material with a high tenacity, and thus suitable
for a lightweight construction with glass‐like transparency. Due to these advantageous
properties, PC is often used in industry for example in medical devices, automotive
headlamps, sporting equipment, electronics, and a variety of other products. PC
is often subjected to uniaxial and biaxial loading conditions. Therefore, reliable
material models have to take into account the various resulting experimental effects.
For those reasons, we investigate PC specimens under uniaxial and biaxial loading
by using different stretch rates and loading scenarios. In addition to that, we
propose methods for optical measurement of local stretches to obtain the approximated
local true stress. In future work, the displacement fields and the resulting reaction
forces will be used for parameter identification of constitutive equations.
