Abstract

The physical principles of the polarization-optical method for studying stresses that is commonly called the photoelasticity method are considered. Using the model of a linear oscillator it is established that the birefringence effect observed in some materials during their deformation can be explained by a shift in the eigenfrequencies of the oscillators, namely charged particles inside the deformed body.

This approach has been used in determining the parameters of the pair interaction potential, in particular, the Mie potential using the experimentally determined birefringence value. The expression for the shape of the strain-optical coefficient, that is, a quantity that serves to relate the difference in the principal deformations and the relative path difference is obtained.
