Software PhotoStress, elaborated in our laboratories allows determination of directions and magnitudes of strains or principal normal stresses in loaded photoelastically coated structural elements. It allows accelerating process of measurement and evaluation of deformations or stresses in point, along line or along curve, respectively. In those entities can be determined directions, and magnitudes of differences and separated principal deformations or stresses on the basis of photography of loaded photoelastically coated objects. In the paper is given procedure for of evaluation of separated principal normal stresses by using of separation methods: method of difference of shear stresses with using separation strain gage and method of oblique incidence.
