摘要：

The object of this work is to discuss a further improvement of the material force method for nonlinear hyperelastostatic fracture mechanics. We investigate the accuracy of the material force method within a 'modified boundary layer'-formulation using a Ramberg-Osgood material type for the sake of comparison. The proposed improvement leads to a reliable and very accurate method to compute the vectorial J-integral in fracture mechanics. Copyright (C) 2003 John Wiley Sons, Ltd.
