text: In order to reduce the fuel consumption and consequently the greenhouse emissions,
the automotive industry is implementing lightweight constructions in the body
in white production. As a result, the use of aluminum alloys is continuously increasing.
Due to poor weldability of aluminum in combination with other materials, mechanical
joining technologies like clinching are increasingly used. In order to predict
relevant characteristics of clinched joints and to ensure the reliability of the
process, it is simulated numerically during product development processes. In
this regard the predictive accuracy of the simulated process highly depends on
the implemented friction model. In particular, the frictional behavior between
the sheet metals affects the geometrical formation of the clinched joint significantly.
This paper presents a testing method, which enables to determine the frictional
coefficients between sheet metal materials for the simulation of clinching processes.
For this purpose, the correlation of interface pressure and the relative velocity
between aluminum sheets in clinching processes is investigated using numerical
simulation. Furthermore, the developed testing method focuses on the specimen
geometry as well as the reproduction of the occurring friction conditions between
two sheet metal materials in clinching processes. Based on a methodical approach
the test setup is explained and the functionality of the method is proven by experimental
tests using sheet metal material EN AW6014.

text: Lithium niobate (LiNbO3), a material frequently used in optical applications,
hosts different kinds of polarons that significantly affect many of its physical
properties. In this study, a variety of electron polarons, namely free, bound,
and bipolarons, are analyzed using first-principles calculations. We perform a
full structural optimization based on density-functional theory for selected intrinsic
defects with special attention to the role of symmetry-breaking distortions that
lower the total energy. The cations hosting the various polarons relax to a different
degree, with a larger relaxation corresponding to a larger gap between the defect
level and the conduction-band edge. The projected density of states reveals that
the polaron states are formerly empty Nb 4d states lowered into the band gap.
Optical absorption spectra are derived within the independent-particle approximation,
corrected by the GW approximation that yields a wider band gap and by including
excitonic effects within the Bethe-Salpeter equation. Comparing the calculated
spectra with the density of states, we find that the defect peak observed in the
optical absorption stems from transitions between the defect level and a continuum
of empty Nb 4d states. Signatures of polarons are further analyzed in the reflectivity
and other experimentally measurable optical coefficients.

text: Modern forming processes often allow today the efficient production
of complex parts. In order to increase the sustainability of forming processes
it would be favorable if the forming of workpieces becomes possible using production
waste. At the Chair of Forming and Machining Technology of the Paderborn University
(LUF) research is presently conducted with the overall goal to produce workpieces
directly from secondary aluminum (e.g., powder and chips). Therefore, friction-based
forming processes like friction spinning (or cognate processes) are used due to
their high efficiency. As a pre-step, the production of semi-finished parts was
the subject of accorded research work at the LUF. Therefore, a friction-based
hot extrusion process was used for the full recycling or rework of aluminum chips
into profiles. Investigations of the recycled semi-finished products show that
they are comparable to conventionally produced semi-finished products in terms
of dimensional stability and shape accuracy. An analysis of the mechanical properties
of hardness and tensile strength shows that a final product with good and homogeneously
distributed properties can be produced. Furthermore, significant correlations
to the friction spinning process could be found that are useful for the above-mentioned
direct part production from secondary aluminum.

text: Driven by the CO2-emission law by the European government and the increasing
costs for raw materials as well as energy, the automotive industry is increasingly
using multi-material constructions. This leads to a continuous increase in the
use of mechanical joining techniques and especially the self-piercing riveting
is of particular importance. The reason for this is the wide range of joining
possibilities as well as the high load-bearing capacities of the joints. To be
able to react to changing boundary conditions, like material thickness or strength
variation of the sheets, research work is crucial with regard to the increase
of versatility. In this paper, a numerical study of the influences on the selfpiercing
riveting process is presented. For this purpose, the influence of different process
parameters such as rivet length and die depth on various quality-relevant characteristics
were investigated. With the help of the design of experiment, significant influences
were determined and interactions between the individual parameters are shown.

text: In many areas of product manufacturing constructions consist of individual
components and metal sheets that are joined together to form complex structures.
A simple and industrial common method for joining dissimilar and coated materials
is clinching. During the joining process and due to the service load cracks can
occur in the area of the joint, propagate due to cyclic loading and consequently
lead to structural failure. For the prevention of these damage cases, first of
all knowledge about the fracture mechanical material parameters regarding the
original material state of the sheet metals used within the clinching process
are essential.Within the scope of this paper experimental and numerical preliminary
investigations regarding the fracture mechanical behavior of sheet metals used
within the clinching process are presented. Due to the low thickness of 1.5 mm
of the material sheets, the development of a new specimen is necessary to determine
the crack growth rate curve including the fracture mechanical parameters like
the threshold against crack growth ΔKI,th and the fracture
toughness KIC of the base material HCT590X. For the experimental
determination of the crack growth rate curve the numerical calculation of the
geometry factor function as well as the calibration function of this special specimen
are essential. After the experimental validation of the numerically determined
calibration function, crack growth rate curves are determined for the stress ratios
R = 0.1 and R = 0.3 to examine
the mean stress sensitivity. In addition, the different rolling directions of
0° and 90° in relation to the initial crack are taken into account in order to
investigate the influence of the anisotropy due to rolling.

text: AbstractIn addition to the classical strength
calculation, it is important to design components with regard to fracture mechanics
because defects and cracks in a component can drastically influence its strength
or fatigue behavior. Cracks can propagate due to operational loads and consequently
lead to component failure. The fracture mechanical analysis provides information
on stable or unstable crack growth as well as about the direction and the growth
rate of a crack. For this purpose, sufficient information has to be available
about the crack location, the crack length, the component geometry, the component
loading and the fracture mechanical material parameters. The fracture mechanical
properties are determined experimentally with standardized specimens as defined
by the guidelines of the American Society for Testing and Materials. In practice,
however, especially in the context with damage cases or formed material fracture
mechanical parameters directly for a component are of interest. However, standard
specimens often cannot be extracted at all due to the complexity of the component
geometry. Therefore, the development of special specimens is required whereby
certain arrangements have to be made in advance. These arrangements are presented
in the present paper in order to contribute to a holistic investigation chain
for the experimental determination of fracture mechanical material parameters
with special specimens.

text: Powder X-ray diffraction (XRD) patterns of ordered mesoporous CMK-8 and CMK-9
carbon materials are simulated by geometric modeling. The materials are amorphous
at the atomic length scale but exhibit highly symmetric gyroidal structures at
the nanometer scale, corresponding to regular, continuous nanopore systems with
cubic symmetry. Their structures lead to characteristic low-angle XRD signatures.
We introduce a model based on geometrical considerations to simulate CMK-8 and
CMK-9 structures with variable volume fraction of carbon (vs. pore volume, i.e.,
variable 'pore wall thickness'). In addition, we also simulate carbon materials
with variable amounts of guest species (e.g., sulfur) residing in their pores.
The corresponding XRD patterns are calculated. The carbon volume fraction turns
out to have a significant impact on the relative diffraction peak intensities,
especially in case of CMK-9 carbon that features a bimodal porosity. Likewise,
the presence of guest species in the pores may also strongly affect the relative
peak intensities. Our study suggests that careful evaluation of experimental low-angle
XRD patterns of (real) CMK-8 or CMK-9 materials offers an opportunity to obtain
detailed information about the nanostructural properties in addition to the mere
identification of the pore systems geometry.

text: A comparison of infrared spectroscopic analytical approaches was made in order
to assess their applicability for internal structure characterization of SiO2
thin films. Markers for porosity and/or disorder based on the analysis of the
asymmetric stretching absorption band of SiO2 between 900−1350 cm−1 were discussed.
The shape of this band, which shows a well-defined LO–TO splitting, depends not
only on the inherent characteristics of the film under analysis but also on the
particular geometry of the IR experiment and the specific surface selection rules
of the substrate. Three types of SiO2 thin films with clearly defined porosity
ranging from dense films to mesoporous films were investigated by transmission
(at different incidence angles), direct specular reflection (at different angles),
and diffuse reflection. Two different types of substrate, metallic and semiconducting,
were used. The combined effect of substrate and specific technique in the final
shape of the band, was discussed, and the efficacy for their applicability to
the determination of porosity in thin SiO2 films was critically evaluated.
