On the Kinematics of Finite Strain Plasticity
Abstract
In this paper, the representation of the kinematics of inelastic flow problems involving finite strains and rotations is discussed. The concept of multiplicatively decomposing the deformation gradient into elastic and plastic components is utilized, where the plastic deformation gradient represents a stress-free, relaxed configuration. Here, it is demonstrated that the choice of relaxed configuration is not essential in the problem solution. Therefore, the kinematic decomposition of elastic-plastic deformation may be chosen to best analyze the specific material model of concern. This is demonstrated by analyzing two specific materials, the planar single crystal and the glassy polymer, using various kinematic representations.
