  • Algorithm and results of the numerical estimation of the effective mechanical properties of double-layer rubber-cord composite

    "The mechanical properties of the rubber-cord composite in strengh analysis are described. There is an algorithm of the numerical estimation of the effective (average) properties of the rubber-cord. The effective properties are defined by the successive application of different deformations to the representative volume of the rubber-cord composite (tensions along each coordinate axis and shifts in each cooridinate planes). The effective properties are defined in form of the generalized Hooke's law (for anisotropic materials). A serias of computations in estimatition of the effective properties of double-layer rubber-cord composite was carried out based on the proposed algorithm. The dependence of the effective elastic modules of rubber-cord on the angle of cord was explored. The according graphs are represented in the article."
