Geometrical moire method for displaying directly the stress field of a circular disk

摘要

In this paper, a geometrical moire method for displaying directly isochromatics and isoclinics of a diametrically pressed circular disk is presented. It is demonstrated that by using two identical or different Wulff nets (or grids) not only the stress fields of a circular disk can be displayed, but the u- and v-displacement fields can be also produced.
