Abstract

For numerical analyses of fracture mechanics problems often a combination of the finite element method with a post processor program for the evaluation of J‐integral values is used. Instead of calculating a line integral as originally proposed by RICE it is reasonable to evaluate surface or volume integrals (for two or three dimensional calculations, respectively) in this case.

In this paper 3D‐formulations proposed by DE LORENZI and ATLURI are considered and several possibilities of the numerical realisation of these formulations are described. While the De Lorenzi proposal is contained as subroutines in the GRS‐version of the standard finite element program ADINA, the Atluri formulation is used in separate post‐processing programs developed by GRS.

As a first application three‐dimensional calculations of a compact‐tension‐shear specimen are considered.
