The research of stress-strain state of dispersedly fiiled polymer composite using the 3d-models

Abstract:

Pending last years the elaborations of numerical methods in respect to design processes of warping and destruction the filled polymer composites (FPC) with the glance of their structure became more active. The much attention gives to reduction of multiple-factor experiments where the parameters (the forms, the sizes, the concentration, the faction etc) of filling material structure vary for improvement of mechanical characteristics of the filled polymer composites. The real structure of material replaces rated model where the mechanism of article on location straining under force loading is simulated. The particles of filler regularly or irregularly place in polymer matrix (PM) and composite stress-strain state (SSS) researches by mechanic of heterogeneous mediums methods. The model forming is the key element of such problem solution by computer technology. In practice mainly the 2D-models are used where the conditions of plane strain or plane stress state realize. But the filling material particles have 3D-configuration (spherical, elliptical, polyhedral and so on). The application of 2D-models leads to falsification of real situation of SSS in FPC. Therefore it is more reasonable 3D-models that allow reproduce (completely or partially) the features of interaction different 3D-configurations particles fasten with the matrix. The reasonability of using 3D-models for filled composites marks in publications of domestic and foreign researchers. The results of SSS filled composite analysis are discussed in present report.
