Abstract:

The paper deals with a method that overcomes the difficulties encountered when the freezing methods of three-dimensional photoelasticity are used. The new method uses a material with Poissons ratio equal to about 0.4. Since the deformations are relatively large, of the order of 1 and the material is not incompressible, mechanical or moire measurements can be used to supplement birefringence measurements. If desired the method can be self sufficient and solve completely three-dimensional problems using only mechanical or moire measurements. A sphere subjected to diametral loading is used to illustrate the application of the method and the precision of the results obtained. Modified author abstract
