To the description of crystallizing polymer material'S deformation with regard to large deformations

Constitutive relations for crystallizing an elastic material, taking into account finite strains is proposed. The linearization procedure for solving boundary value problems with large deformations, which allows to introduce the thermal deformation and deformation of the structural shrinkage of the material is considered. The efficiency of the model is tested on tasks of simple shear and uniaxial strain.
