Modeling of damage behavior in microstructured solids with focus on metals and composites

IMACM-Talk

FG Mathematik / IMACM

This talk deals with the computational modeling of damage in microstructured solids,in particular metals and composites. At a small enough scale, all natural and synthe tic materials are heterogeneous. That is, they are either composed of domains of different materials, such as a composite, or the same material in different  states,such as a polycrystal. The properties of a heterogeneous material depend onmicrostructural features. In this presentation, we discuss modeling related issuespertaining to the geometric arrangement of the constituents as well as  on how tomodel various damage mechanisms. The models are all based on continuummechanical theories and capture features such as tension-compression asymmetry,interface and/or interphase behavior, crack propagation, size-dependence, plasticity,matrix-inclusion interactions, anisotropy. As example, polycrystals, metallic glassesand composites are discussed. Comparison to experimental data is given.
