Modeling and simulation of phase transformations in polycrystals -- a micro-sphere framework
Richard Ostwald (TU Dortmund University), Thorsten Bartel (TU Dortmund University), Andreas Menzel (TU Dortmund University)
Kurzfassung:
A new framework for the simulation of shape memory alloys (SMA) and TRIP steels undergoing martensite-austenite phase transformations is introduced. The goal is the derivation and elaboration of a generalised model which facilitates the reflection of the characteristic macroscopic behaviour of SMA as well as of TRIP steels. The model is implemented in a micro-sphere formulation in order to capture polycrystalline behaviour and to simulate three-dimensional boundary value problems.

Topology Optimization of Nonlinear Problems in Solid and Fluid Mechanics
Kurt Maute (University of Colorado Boulder)
Kurzfassung:
Accurately modeling nonlinear problems in solid and fluid mechanics and, at the same time, allowing for topological changes in the optimization process poses interesting challenges on the formulation of the optimization problem, the physics model, and the discretization method. This talk will provide an overview of topology optimization approaches for nonlinear mechanical problems, focusing on level set methods with immersed boundary discretization techniques. Recent advances for problems in finite strain solid mechanics and fluid mechanics will be presented.
