摘要：

This paper presents an a posteriori error estimator for mixed-mode stress intensity factors in plane linear elasticity. A surface integral over an arbitrary crown is used for the separate calculation of the combined mode's stress intensity factors. The error in the quantity of interest is based on goal-oriented error measures and estimated through an error in the constitutive relation. Copyright (c) 2006 John Wiley & Sons, Ltd.
