Abstract

Photoelasticity is the most promising experimental method of the mechanics of solids. In recent years this method has been used successfully on linear and nonlinear viscoelastic problems and on problems of lattice-nonhomogeneous medium. the further development of photoelasticity is concerned with nonlinear mechanics of nonelastic and composite materials, especially at finite and large deformations. The creation of the photoelastic methods is connected with choice or synthesis of birefringent material, having needed properties. It is necessary also to formulate basic stress-strain-optic relations, to work out procedures of model experimental studies, to develop methods of principal stresses and strains separation, to create similarity theories. In this paper the methods of orthotropic linear photoviscoelasticity, photoviscoplasticity, and some aspects of nonlinear photoelasticity are considered.
