Semi-smooth Newton method for nonassociative plasticity using the bi-potential approach

Résumé

This paper presents an implicit solver for non-associative plasticity problems based on the semi-smooth Newton method. The method is derived from the Implicit Standard Material and is easily compatible with various space discretization techniques, particularly the Material Point Method and the Finite Element Method. The solver converges quadratically, even for large time steps, although theoretical results have only been demonstrated for restricted cases. The method is exemplified through a footing simulation.
