Paper Abstract

A computer-oriented hybrid method will be described to determine the principal stresses in plane objects, which are composed to different materials by means of photoelastic experiments. The difference of the principal stresses is obtained by digital image processing of the isochromatic fringe pattern, the sum of the principal stresses is calculated by means of the boundary element method. Thus the values of the principal stresses in arbitrary points of the object are given without needing the isoclines. These are necessary now only to get information on the direction of the stress tensor axes.
