Elastic-Plastic Contact Modeling. Part I: Algorithm Overview and Assessment of Plastic Strain Increment
A fast algorithm for elastic-plastic contact simulation is overviewed in this paper. Betti’s reciprocal theorem is employed to assess surface normal displacement and stress state in an elastic half-space in the presence ...
Elastic-Plastic Contact Modeling. Part II: Numerical Simulations and Program Validation
Elastic plastic spherical contact is simulated using an algorithm proposed in a companion paper. Materials of contacting bodies are assumed to have different behaviours: rigid (R), elastic (E), elastic-plastic with isotropic ...
