Direct crystal plasticity model: Application to the investigation of single crystal fragmentation under uniaxial loading

摘要

The mathematical formulation and the results of solving a boundary value problem of uniaxial loading of single-crystal aluminum samples are reported. A first-type direct model was used for the solution of the boundary value problem. The material response is determined within the crystal elastoviscoplasticity theory. The fragmentation of the initially homogeneous sample into zones with different internal structure evolution is shown.
