Abstract

The work considers a procedure for determining stress intensity factors of types I and II under combined loading on the basis of processing a two-dimensional normal displacement field, obtained by holographic interferometry. This procedure is based on obtaining the analytical idea of a stress field in a crack tip area which corresponds to the experimentally found pattern of isopahs. A case of crack edge loading by arbitrary distributed load is explained.
