"Micromechanics of Polycrystals: Full-Field Computations and Second-order Homogenization Approaches"

January 27 @ 3:00 PM - 4:00 PM - Birck 1001

 Abstract:
Models based on crystal plasticity are increasingly used in engineering applications. Three key elements of these methods are: 1) a proper consideration of the plastic deformation mechanisms at single crystal level; 2) a representative description of the polycrystalmicrostructure, and 3) an appropriate scheme to connect the microstates in the crystallites and the polycrystalresponse. The latter can be based on homogenization, which rely on a statistical description of the microstructure, or be full-field solutions, which requires a spatial description of the microstructure.
