Cyclic Behavior of Simple Models in Hypoplasticity and Plasticity with Nonlinear Kinematic Hardening

The paper gives insights into modeling and well-posedness analysis driven by cyclic behavior of particular rate-independent constitutive equations based on the framework hypoplasticity elastoplastic concept with nonlinear kinematic hardening. Compared to classical elastoplasticity, in there is no need decompose deformation elastic plastic parts. two different types approaches show some similarities structure relations, which are relevant for describing irreversible material properties. These models exhibit unlimited ratchetting under loading. In numerical simulation it will be demonstrated, how a shakedown loading can achieved slightly enhanced simple hypoplastic proposed Bauer
