Title:Adaptive discontinuous Galerkin method for viscoplastic analysis
Author(s):Fang, Biao; Carranza, Fernando L.; Haber, Robert B.
Subject(s):Viscoplastic Analysis
H-adaptive Discontinuous Galerkin Method
Abstract:This paper describes an h-adaptive, space-time discontinuous Galerkin finite element method for quasi-static viscoplastic response in a time-varying domain. The equations of equilibrium and the evolution equations in the viscoplastic material model comprise an elliptic/ hyperbolic system. We focus here on two aspects of the model: stabilization of the hyperbolic subproblem and residual-based error estimates and adaptive algorithms for viscoplastic analysis.
