To prevent stress concentration it is of considerable interest that the body contour be found whose portions show no preference to brittle failure or plastic deformation. Such contours are called by us “equally rigid.” Two-dimensional problems are considered for finding the “equally rigid” form of the hole in an anisotropic medium. The lack of stress concentration on the coutour of the hole is the criterion which decides whether or not the hole is “equally rigid.” For an isotropic medium this converse problem of elasticity theory was solved in .
