An implicit formulation of the Bodner-Partom constitutive equations
(2003) In Computers & Structures 81(13). p.1405-1414- Abstract
- The framework for an implicit implementation of the Bodner-Partom material model is presented. All equations needed for using a Newton-Raphson algorithm to solve the stress and hardening equations at the integration points are derived. In addition, the algorithmic tangential stiffness tensor, ensuring quadratic convergence in the global loop is presented.
