โœฆ Synopsis

This paper presents the "Inverse Plexibility Method" which allows substantial gain in time when computing energy release rates (or stress intensity factors) for various lengths of a growing crack. Reduction ratio is of order of ten compared with classical methods. Despite the relative coarseness of meshes used, when practicing finite element analysis, accuracy of results remains good as shown by examples presented (metallic cracked plate and composite specimens).
