Abstract:

This paper deals with means of applying known displacements and known stresses to the boundaries of models used in experimental stress analysis. The solution of several problems in which means are used, is reviewed. The evaluation of the stresses, strains, and displacements in the field is conducted using several experimental stress analysis methods. Particular emphasis is placed on the methods used to study several kinds of shrinkage problems with two- and threedimensional photoelasticity. The application of these methods is illustrated with examples, several of which are in the field of stress analysis of solid propellant grains. Author
