F=FeFp? A kinematic analysis of finite elastoplasticity

The kinematic description of finite elastoplasticity based on the decomposition F=FeFp is currently standard in the continuum mechanics community. Besides its acceptance, many issues have remained unresolved, such as the uniqueness of the decomposition, the characterization of the plastic deformation without reference to the intermediate configuration or its micromechanical understanding. In this talk, we will unveil some of these issues via a careful kinematic analysis of elastoplastic deformations at the microscale.
