NCP Function-Based Dual Weighted Residual Error Estimators for Signorini's Problem

Abstract

In this paper, we onsider goal-oriented adaptive nite element methods for Signorini's problem. The basis is a mixed formulation, whi h is reformulated as nonlinear variational equality using a nonlinear omplementarity (NCP) fun tion. For a general dis retization, we derive error identities with respe t to a possible nonlinear quantity of interest in the… (More)
