MATHEMATICAL MODELING OF PROCESSES DEVELOPMENT OF CRITERIA FOR RELIABILITY OF THE PREDICTION OF THE DEFORMATION AND RELAXATION PROCESSES OF POLYMERIC MATERIALS

摘要

The problems of the reliability of the prediction of the relaxation and deformation properties of polymer materials in the region of action of nondestructive loads close to the conditions of their operation are considered on the basis of mathematical modeling of the relaxation and creep processes. For practical evaluation of the reliability of this prediction, integral criteria are obtained on the basis of the determining equations of deformation and relaxation processes of these materials.
