AN EXPERIMENTAL METHOD TO ANALYZE GRAVITATIONAL STRESSES IN TWO-DIMENSIONAL PROBLEMS.

Abstract

Stresses and strains in a circular disk, in an OD/ID = 2 circular ring and in a circular disk with a star-shaped perforation, all made of a polyurethane rubber and subjected to the action of gravity, were analyzed by means of photoelasticity and moire. Some of the results obtained for the ring are compared with theoretical results. Stresses for the inside and outside boundaries of the circular disk with a star-shaped perforation, are given in dimensionless form. The method should be applicable to the solution of many stress problems in which stresses are produced by gravity. (Author)
