Abstract

A hypersingular Green's function generation for fracture mechanics problems J.C.F. Telles, G.S. Castor & S. Guimaraes , CEf 2J&f5-970, #20 (fe SUMMARY A boundary element formulation to deal with fracture mechanics problems can be obtained with the implementation of the associated Green's function acting as the fundamental solution. The range of applications of this formulation is dependent on the availability of the appropriate Green's function for actual crack geometry. Analytical Green' s functions have been presented for a few single crack configurations in 2-D applications and require complex variable theory. The present work extends the applicability of the formulation through the introduction of efficient numerical means of computing the Green's function components for single or multiple crack problems, of general geometry. Also, the approach uses real variables only and well established
