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: The components of a body in white consist of many individual thin-walled sheet
metal parts, which usually are manufactured in deep-drawing processes. In general,
the conditions in a deep-drawing process change due to changing tribology conditions,
varying degrees of spring back, or scattering material properties in the sheet
blanks, which affects the resulting pre-strain. Mechanical joining processes,
especially clinching, are influenced by these process-related pre-strains. The
final geometric shape of a clinched joint is affected to a significant level by
the prior material deformation when joining with constant process parameters.
That leads to a change in the stiffness and force transmission in the clinched
joint due to the different geometric dimensions, such as interlock, neck thickness
and bottom thickness, which directly affect the load bearing capacity. Here, the
influence of the pre-straining in the deep drawing process on the force distribution
in clinch points in an automotive assembly is investigated by finite-element models
numerically. In further studies, the results are implemented in an optimization
tool for designing clinched components. The methodology starts with a pre-straining
of metal sheets. This step is followed by 2D rotationally symmetric forming simulations
of the joining process. The resulting mesh of each forming simulation is rotated
and 3D models are obtained. The clinched joint solid model with pre-strains is
used further to determine the joint stiffnesses. With the simulation of the same
test set-up with an equivalent point-connector model, the equivalent stiffness
for each pre-strain combination is determined. Simulations are performed on a
clinched component to assess the influence of pre-strain and sheet thinning on
the clinched joint loadings by using the equivalent stiffnesses. The investigations
clearly show that for the selected component, the loadings at the clinch points
are dependent on the sheet thinning and the stiffnesses due to pre-strain. The
magnitude of the influence varies depending on the quantity considered. For example,
the shear force is more sensitive to the joint stiffness than to the sheet thinning.

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: Confidence in additive manufacturing technologies is directly related to the
predictability of part properties, which is influenced by several factors. To
gain confidence, online process monitoring with dedicated and reliable feedback
is desirable for every process. In this project, a powder bed monitoring system
was developed as a retrofit solution for the EOS P3 laser sintering machines.
A high-resolution camera records each layer, which is analyzed by a Region-Based
Convolutional Neural Network (Mask R-CNN). Over 2500 images were annotated and
classified to train the network in detecting defects in the powder bed at a very
high level. Each defect is checked for intersection with exposure areas. To distinguish
between acceptable imperfections and critical defects that lead to part rejection,
the impact of these imperfections on part properties is investigated.

text: By monitoring the recoating process within polymer laser sintering production,
it was shown that multiple powder-spread-flaws can be detected. Those groove-like
flaws are expected to be the result of agglomerates jamming between the recoater
and the last powder layer. This work is analyzing the interaction between powder-spread-flaws
and part properties, showing the influence of the recoating process on the performance
of laser sintering parts. Therefore, artificial powder-spread-flaws are applied
to the build jobs of tensile test specimens which are measured and analyzed regarding
the elongation at break, strength and fracture position. For the characteristics
of the flaws, the artificial grooves are varied in depth and width. Furthermore,
the position of the flaw is changed form mid part to close to surface areas. It
was shown, that several flaws are visible at the part surface, resulting in stress
concentration and reduced performance. But there are as well parts with flaw-layers,
which are not visible after the build process on the part. Those parts can have
significantly reduced mechanical properties as well.

abstract:
- lang: eng
text: This paper presents preliminary work on the formalization of three prominent
cognitive biases in the diagnostic reasoning process over epileptic seizures,
psychogenic seizures and syncopes. Diagnostic reasoning is understood as iterative
exploration of medical evidence. This exploration is represented as a partially
observable Markov decision process where the state (i.e., the correct diagnosis)
is uncertain. Observation likelihoods and belief updates are computed using a
Bayesian network which defines the interrelation between medical risk factors,
diagnoses and potential findings. The decision problem is solved via partially
observable upper confidence bounds for trees in Monte-Carlo planning. We compute
a biased diagnostic exploration policy by altering the generated state transition,
observation and reward during look ahead simulations. The resulting diagnostic
policies reproduce reasoning errors which have only been described informally
in the medical literature. We plan to use this formal representation in the future
to inversely detect and classify biased reasoning in actual diagnostic trajectories
obtained from physicians.
