Numerical Modeling of Heterogeneous Materials in Technological Processes with Experimental Validation

Leuphana Universitat Luneburg
ABSTRACT: The relation between microstructure evolution and macroscopic constitutive response is crucial in the design and modeling of heterogeneous metallic materials. Klusemann addresses various experimental and numerical investigations of heterogeneous materials. This includes crystal plasticity modeling of heterogeneous thin sheet metal specimens, modeling of material instabilities as the Portevin-Le Chatelier effect, and phenomenological modeling of the anisotropic flow behavior of metal sheets. Laser welding techniques are one current focus of his research. The application of a thermo-mechanical material model for precipitation hardened aluminum alloys will be presented and compared to experimental observations in terms of residual stresses and hardness.
