PHOTOELASTIC MODELLING OF DESTRUCTION PROCESSES CONSIDERING THE CREEP

The generalized theory of damage accumulation was used in the damage tensor, based on the true strain, which is defined by a polarization optical method has been constructed. It allows us to find time before the destruction for various deformation processes on the kernels of a damage tensor found from experiences on natural samples. However, there are no effective methods of a quantitative evaluation of damage of viscoelastic materials under the influence of loading, especially in the field of their plastic deformations, by means of experimental nondestructive methods.
