Studies in elastic fracture mechanics based on the material force method. (English) Zbl 1032.74702
Summary: The object of this work is to discuss a further improvement of the material force method for non-linear 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.
