| Title of the article | Model behavior of polymer shape memory |
| Abstract. | There is a large class of steel materials in which the elementary act of conditional permanent deformation is carried out by a reversible martensitic transformation, elastic twinning and a number of other processes, radically changing patterns of inelastic deformation. At present, alloys are found not only, but also polymers having a shape memory effect, however, they are accompanied by deformation of the shape memory and creep deformation. Unlike the case of alloys with shape memory effect to determine all of the mechanical properties of the polymer directly from any private experiments quite a difficult task. Therefore, in order to find the functions in the constitutive relations need to apply the methods of identification. In this paper we consider the problem of behavior of polymer having a shape memory effect and hereditary elasticity. The technique of genetic algorithm for elastic and shape memory materials has been tested for the problem of the tension rod. In determining the stress-strain state of the finite element method was used with an eight isoparametric finite element space. For solutions of the Cauchy problem using the method of Euler. The comparison of the various options of defining relations for a material with shape memory effect. |
