This book provides an overview of the experimental characterization
of materials and their numerical modeling, as well as the
development of new computational methods for virtual design. Its 17
contributions are divided into four main sections: experiments and
virtual design, composites, fractures and fatigue, and uncertainty
quantification. The first section explores new experimental methods
that can be used to more accurately characterize material behavior.
Furthermore, it presents a combined experimental and numerical
approach to optimizing the properties of a structure, as well as
new developments in the field of computational methods for virtual
design. In turn, the second section is dedicated to experimental
and numerical investigations of composites, with a special focus on
the modeling of failure modes and the optimization of these
materials. Since fatigue also includes wear due to frictional
contact and aging of elastomers, new numerical schemes in the field
of crack modeling and fatigue prediction are also discussed. The
input parameters of a classical numerical simulation represent mean
values of actual observations, though certain deviations arise: to
illustrate the uncertainties of parameters used in calculations,
the book's final section presents new and efficient approaches to
uncertainty quantification.

This Festschrift is dedicated to Professor Dr.-Ing. habil. Peter
Wriggers on the occasion of his 70th birthday. Thanks to his high
dedication to research, over the years Peter Wriggers has built an
international network with renowned experts in the field of
computational mechanics. This is proven by the large number of
contributions from friends and collaborators as well as former PhD
students from all over the world. The diversity of Peter Wriggers
network is mirrored by the range of topics that are covered by this
book. To name only a few, these include contact mechanics, finite
& virtual element technologies, micromechanics, multiscale
approaches, fracture mechanics, isogeometric analysis, stochastic
methods, meshfree and particle methods. Applications of numerical
simulation to specific problems, e.g. Biomechanics and Additive
Manufacturing is also covered. The volume intends to present an
overview of the state of the art and current trends in
computational mechanics for academia and industry.
This book provides a detailed instruction to virtually reproduce
the processes of Additive Manufacturing on a computer. First, all
mathematical equations needed to model these processes are
presented. Due to their flexibility, meshfree methods represent
optimal computational solution schemes to simulate Additive
Manufacturing processes. On the other hand, these methods usually
do not guarantee an accurate solution. For this reason, this
monograph is dedicated in detail to the necessary criteria for
computational solution schemes to provide accurate results. Several
meshfree methods are examined with respect to these conditions. Two
different 3D printing techniques are presented in detail. The
results obtained from the simulation are investigated and compared
with experimental data. This work is addressed to both scientists
and professionals working in the field of development who are
interested to learn the secrets behind meshfree methods or get into
the modeling of Additive Manufacturing.
