Elastic Frictional Contact under Normal and Tangential Loading
Spînu, Sergiu; Grădinaru, Dorin (UDJG, 2011)A robust algorithm for elastic contact simulation considering tangential tractions is advanced in this paper. Two similar numerical models are advanced for the normal, as well as for the tangential direction, and the ... -
Elastic-Plastic Contact Modeling. Part I: Algorithm Overview and Assessment of Plastic Strain Increment
Spînu, Sergiu; Diaconescu, Emanuel (UDJG, 2010)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
Diaconescu, Emanuel; Spînu, Sergiu (UDJG, 2010)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 ...
