Paper Abstract

A problem of determination of three-dimensional stress state from optical measurements by the method of integrated photoelasticity is considered. The stress medium is contained in the cylinder domain, the element of the cylinder is parallel to z-axis. Only the equilibrium equations are satisfied and strains are not considered. The weak optical anisotropy is supposed. The optical measurements are carried out along all horizontal straight lines which are parallel to the plane z equals 0. It is proved under this assumption that the longitudinal component (sigma) zz of the stress tensor can be determined. The method of numerical determination is offered. It is proved that no information about stress tensor, except (sigma) zz, can be determined.
