Overview

In many high-performance materials and biomaterials, the damage process under operating conditions is coupled with phase transformation, electrochemical reactions, wear, diffusion and fluid transport, such as degradation and ageing of silicon electrodes in lithium-ion batteries, corrosion fatigue of biodegradable implants and thermomechanical fatigue of high-temperature alloys. In the field of fatigue strength and damage mechanics we focus and develop experimental and numerical methods for the lifetime prediction of the novel high-performance materials and assessment of the mechanical integrity of highly stressed components under complex loads. Based on innovative material testing and numerical approaches, we develop multiscale methods for modelling complex material damage and component failure under consideration of multiphysical effects.
