text: "Abstract\r\n In this study, we
develop a novel multi-fidelity deep learning approach that transforms low-fidelity
solution maps into high-fidelity ones by incorporating parametric space information
into an autoencoder architecture. This method’s integration of parametric space
information significantly reduces the amount of training data needed to effectively
predict high-fidelity solutions from low-fidelity ones. In this study, we examine
a two-dimensional steady-state heat transfer analysis within a heterogeneous materials
microstructure. The heat conductivity coefficients for two different materials
are condensed from a 101 \r\n \r\n
\ $$\\times $$\r\n \r\n ×\r\n
\ \r\n \r\n 101
grid to smaller grids. We then solve the boundary value problem on the coarsest
grid using a pre-trained physics-informed neural operator network known as Finite
Operator Learning (FOL). The resulting low-fidelity solution is subsequently upscaled
back to a 101 \r\n \r\n $$\\times
$$\r\n \r\n
\ ×\r\n \r\n \r\n
\ 101 grid using a newly designed enhanced autoencoder.
The novelty of the developed enhanced autoencoder lies in the concatenation of
heat conductivity maps of different resolutions to the decoder segment in distinct
steps. Hence the developed algorithm is named microstructure-embedded autoencoder
(MEA). We compare the MEA outcomes with those from finite element methods, the
standard U-Net, and an interpolation approach as an upscaling technique. Our analysis
shows that MEA outperforms these methods in terms of computational efficiency
and error on representative test cases. As a result, the MEA serves as a potential
supplement to neural operator networks, effectively upscaling low-fidelity solutions
to high-fidelity while preserving critical details often lost in traditional upscaling
methods, such as sharp interfaces features lost in the context of interpolation
approaches."

text: AbstractThe open-source parameter identification
tool ADAPT (A diversely applicable parameter identification Tool) is integrated
with a machine learning-based approach for start value prediction in order to
calibrate a Gurson–Tvergaard–Needleman (GTN) and a Lemaitre damage model. As representative
example case-hardened steel 16MnCrS5 is elaborated. An artificial neural network
(ANN) is initially trained by using load–displacement curves derived from simulations
of a boundary value problem—instead of using data generated for homogeneous states
of deformation at material point or one-element level—with varying material parameter
combinations. The ANN is then employed so as to predict sets of material parameters
that already provide close solutions to the experiment. These predicted parameter
sets serve as starting values for a subsequent multi-objective parameter identification
by using ADAPT. ADAPT allows for the consideration of input data from multiple
scales, including integral data such as load–displacement curves, full-field data
such as displacement and strain fields, and high-resolution experimental void
data at the micro-scale. The influence of each data set on prediction quality
is analyzed. Using various types of input data introduces additional information,
enhancing prediction accuracy. The validation is carried out with respect to experimental
void measurements of forward rod extruded parts. The results demonstrate, by incorporating
void measurements in the optimization process, that it is possible to improve
the quantitative prediction of ductile damage in the sense of void area fractions
by factor 28 in forward rod extrusion.

text: AbstractRolling processes of conventional
cast Al-Li alloys quickly reach their limits due to relatively poor material formability.
This can be overcome by using twin-roll casting to produce thin sheets. Further
thermomechanical treatment, including hot or cold rolling, and heat treatment
can adjust the mechanical properties of twin-roll cast Al-Li sheets. The whole
manufacturing chain requires detailed knowledge of the precipitation and dissolution
behavior during heating, soaking and cooling, to purposefully select any process
parameters. This study shows the process chain of a twin-roll cast Al–Cu–Li alloy
achieving a hardness of around 180 HV1 by adapting the heat treatment parameters
for homogenisation, hot rolling and age hardening. Both hardness and microstructure
evolution are visualised along the process chain.

text: 'This study evaluates four widely used fracture simulation methods,
comparing their computational expenses and implementation complexities within
the finite element (FE) framework when employed on heterogeneous solids. Fracture
methods considered encompass the intrinsic cohesive zone model (CZM) using zero-thickness
cohesive interface elements (CIEs), the standard phase-field fracture (SPFM) approach,
the cohesive phase-field fracture (CPFM) approach, and an innovative hybrid model.
The hybrid approach combines the CPFM fracture method with the CZM, specifically
applying the CZM within the interface zone. The finite element model studied is
characterized by three specific phases: inclusions, matrix, and the interface
zone. This case study serves as a potential template for meso- or micro-level
simulations involving a variety of composite materials. The thorough assessment
of these modeling techniques indicates that the CPFM approach stands out as the
most effective computational model, provided that the thickness of the interface
zone is not significantly smaller than that of the other phases. In materials
like concrete, which contain interfaces within their microstructure, the interface
thickness is notably small when compared to other phases. This leads to the hybrid
model standing as the most authentic finite element model, utilizing CIEs within
the interface to simulate interface debonding. A significant finding from this
investigation is that within the CPFM method, for a specific interface thickness,
convergence with the hybrid model can be observed. This suggests that the CPFM
fracture method could serve as a unified fracture approach for multiphase materials
when a specific interfacial thickness is used. In addition, this research provides
valuable insights that can advance efforts to fine-tune material microstructures.
An investigation of the influence of interfacial material properties, voids, and
the spatial arrangement of inclusions shows a pronounced effect of these parameters
on the fracture toughness of the material.'

text: Die Auslegung von gefügten Bauteilen ermöglicht die Produktion von Strukturbauteilen,
welche teils aus sehr vielen Einzelteilen bestehen und durch eine hohe Anzahl
von Fügepunkten verbunden sind. Die Eigenschaften der Einzelteile und die Prozessgrößen
in der Fertigung unterliegen Schwankungen, die bei der Auslegung berücksichtigt
werden müssen. Um diese Bauteile stets nach der Spezifikation zu liefern, werden
die Prozesse gewöhnlich über die gesamte Prozesskette überwacht und das Bauteil
überdimensioniert. Treten unvorhersehbare Störungen in der Prozesskette auf, kann
das Bauteil nicht mehr weiter produziert werden. Entweder muss die Störung im
Prozess behoben werden, was nicht immer möglich ist und die schon teils produzierte
Charge muss vernichtet werden, oder der Teil der Prozesskette nach der Störung
muss angepasst werden. Dies kann z.B. durch eine Änderungskonstruktion, wie der
Anpassung der Fügepunktpositionen und der -anzahl, geschehen. In dieser Dissertation
wurde eine Auslegungsmethode zur strukturellen elastischen Auslegung punktgefügter
Bauteile entwickelt, mit der eine Anpassungskonstruktion, z.B. auf solche Störungen,
möglich ist. Diese Methode basiert auf der Ausnutzung des Einflusses von geometrischen
Bauteilgrößen, wie z.B. der Bauteildicke und der Fügepunktpositionierung, von
veränderten Fügepunkteigenschaften sowie dem Verständnis zwischen Prozessgrößen
und den erzeugten Fügepunkteigenschaften.

text: The design of joined components enables the production of structural components,
which consist of many individual parts and are combined by a large number of joining
elements. Since the properties of the individual parts and the process parameters
in manufacturing can scatter, the deviations must be considered in the design.
To always deliver these components according to specification, the processes are
usually monitored over the entire process chain and the component is over dimensioned.
If unforeseeable disruptions occur in the process chain, the component can no
longer be produced. Either the malfunction in the process must be rectified, which
is not always possible, and the batch that has already been partially produced
must be destroyed, or the part of the process chain after the malfunction needs
to be adjusted. This can be done, for example, by changing the design, such as
adjusting the joints positions and number. In this PhD thesis, a design method
for structural elastic designing of point-joined components was developed. With
that method a revised design can be defined, e.g. in order to meet unforeseeable
disruptions in the process chain. This method is based on the utilization of the
influence of geometric component parameters, such as component thickness and joint
positioning, on changed joint properties as well as on the understanding between
process parameters and the manufactured joint properties.
