Implementation of Combined Ohno-Wang Nonlinear Kinematic Hardening Model and Norton-Bailey Creep Model Using Partitioned Stress Integration Technique

摘要

The formulation of stress integration and the consistent tangent matrix for the combined Ohno-Wang and Norton-Bailey constitutive model is derived and it is implemented using a partitioned stress integration technique. The constitutive equation is included in a finite element analysis code, ADVENTURE_Solid Ver. 2, and it is verified by solving a simple illustrative example with one hexahedral element.
