Consistent Tangent Stiffness for Nonlocal Damage Models

Original language description

This paper deals with the computational analysis of strain localization problems using nonlocal continuum damage models of the integral type. The general framework for a consistent derivation of the "nonlocal"angent stiffness is presented. The propertiesof the tangent stiffness matrix are discussed and the corresponding assembly procedure is described. The quadratic rate of convergence of the Newton-Raphson interation procedure is demonstrated and the efficiency of the proposed technique is compared tothe standard approach based on the secan or elastic stiffness matrices. In this context, performance of direct and interative solvers for the linearized equilibrium equations is also examined
