Abstract:

The results are presented of a relaxational analysis of the elastic and plastic stress fields in an externally notched specimen. Stress distributions in the vicinity of the crack and the plastic enclaves for a sequence of applied loads are given along with numerical data these are compared to an approximate elastic solution. Taken together, the relaxational and elastic solutions will enable t computation of strains and strain energies leading to a ductile failure criterion. Author
