Paper Abstract

The optical method of caustics has been successfully applied to several two dimensional elasticity problems. Up to now, this method can't treat of more complicated three dimen-sional elasticity problems. In this paper, the experimental technique of caustics is developed, and caustics are produced by annealing the stress-frozen slices. Applied the technique to Boussinesq's problem of a normal force and Cerruti's problem of a tangential force on the plane surface of a half-space, the experimentally obtained caustics for these problems were seen to be in satisfactory agreement with the corresponding theoretical forms. The treatment of more complicated three dimensional elasticity problems, including crack problems, by the author's method is also possible.
