Abstract
This paper presents a comparative study of a series of flux projection type error estimators for elastio-plastic materials undergoing large strains and large rotations. The error estimators are: L2 norms of stress error, total strain error, equivalent strain error, incremental total strain error per load step, and energy rate norm error, respectively. Numerical examples are presented in two dimensions. The information provided by these error estimators may be used for adaptive mesh refinement and for subsequent data transfer (rezoning) in a large deformation analysis. The error estimators based on the energy rate and the incremental total strain were found to be accurate in the prediction of the discretization error for the test cases considered. The L2 norm of incremental strain error estimator consistently gave the most conservative estimate of error.
