STRUCTURAL SIMULATION OF THE ELASTIC AND ELASTICO-PLASTIC PROPERTIES OF POLYMER/SILICATE NANOCOMPOSITES UNDER FINITE DEFORMATIONS
RÉSUMÉ
The article presents the results of computer simulation of the mechanical behavior of polymer/silicate nanocomposites under finite deformations. The filler particles represented stacks of several parallel ultrathin silicate plates separated by layers of the polymer, the matrix was a nonlinear-elastic or elastico-plastic material. The stressed-deformed state around a separate inclusion was investigated depending on its orientation to the outer loading and the properties of the matrix. For this purpose, the problem on homogeneous stretching of a periodicity cell in the form of a rectangular region with an inclusion at the center was solved. The conditions under which the bending stability of the particle is loss in the process of macrostretching were determined. Based on the solutions obtained, the effective mechanical characteristics of the nanocomposite were estimated depending on the properties of the matrix, the degree of filling, and on the orientation of particles. The corresponding dependences are plotted.
