Abstract

In this paper, a geometrical moiré 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- displacemet fields can be also produced.
