  text: Predicting the durability of components subjected to mechanical load under
    environmental conditions leading to corrosion is one of the most challenging tasks
    in mechanical engineering. The demand for precise predictions increases with the
    desire of lightweight design in transportation due to environmental protection.
    Corrosion with its manifold of mechanisms often occurs together with the production
    of hydrogen by electrochemical reactions. Hydrogen embrittlement is one of the
    most feared damage mechanisms for metal constructions often leading to early and
    unexpected failure. Until now, predictions are mostly based on costly experiments.
    Hence, a rational predictive model based on the fundamentals of electrochemistry
    and damage mechanics has to be developed in order to reduce the costs. In this
    work, a first model approach based on classical continuum damage mechanics is
    presented to couple both, the damage induced by the mechanical stress and the
    hydrogen embrittlement. An elaborated two-scale model based on the selfconsistent
    theory is applied to describe the mechanical damage due to fatigue. The electrochemical
    kinetics are elucidated through the Langmuir adsorption isotherm and the diffusion
    equation to consider the impact of hydrogen embrittlement on the fatigue. The
    modeling of the mechanism of hydrogen embrittlement defines the progress of damage
    accumulation due to the electrochemistry. The durability results like the S-N
    diagram show the influence of hydrogen embrittlement by varying, e.g. the fatigue
    frequency or the stress ratio.

  text: Due to economic and ecological requirements and the associated trend towards
    lightweight construction, mechanical joining technologies like self-piercing riveting
    are gaining in importance. In addition, the increase in lightweight multi-material
    joints has led to the development of many different mechanical joining technologies
    which can only be applied to join a small number of material combinations. This
    leads to low process efficiency, and in the case of self-piercing riveting, to
    a large number of required tool changes. Another approach focuses on reacting
    to changing boundary conditions as well as the creation of customised joints by
    using adaptive tools, versatile auxiliary joining parts or modified process kinematics.
    Therefore, this study investigates the influence of increased die-sided kinematics
    on joint formation in self-piercing riveting process. The aim is to achieve an
    improvement of the joint properties by superimposing the punch feed. Furthermore,
    it is intended to reduce required tool changes due to the improved joint design.
    The investigations were carried out by means of a 2D-axisymmetric numerical simulation
    model using the LS-Dyna simulation software. After the validation of the process
    model, the die was extended to include driven die elements. Using the model, different
    kinematics as well as their effects on the joint formation and the internal stress
    concentration could be analysed. In principle, the increased actuator technology
    enabled an increase of the interlock formation for both pure aluminium and multi-material
    joints consisting of steel and aluminium. However, the resulting process forces
    were higher during the process phases of punching and spreading.
