FEM Implementation of Unified Viscoplastic Chaboche Model
Original language description
The implementation of a viscoplastic Chaboche type material model in the framework of the finite element method (FEM) is presented in this paper. The multiaxial version of unified viscoplastic Chaboche model is implemented as a user-defined material subroutine for commercial finite element software Abaqus. Based on the implicit (backward) Euler method, the elastic predictor and viscoplastic corrector methodology is used, constitutive equations are solved in the local Newton iterative method. The material model is implemented together with the consistent tangent operator, which is derived completely for the first time, ensuring quadratic convergence of the global Newton scheme. Finally, the implemented material model is used to predict a fatigue and creep damage of thermo-mechanically loaded turbocharger turbine housing.
