A NEW RUBBER-CORD COMPOSITE MODEL AND THE CORRESPONDING PARAMETER IDENTIFICATION SCHEME

In order to provide a simple and effective numerical computation method, a rubber-cord composite model is presented in this article. Firstly the finite element formula of this model are deduced and implemented into the user platform of ABAQUS software; then based on the FEA result of an unit cell, the long fiber reinforced composite containing hyperelastic matrix is assumed to be equivalent to a transversely isotropic hyperelastic material. A numerical example is given to compare the results obtained using the equivalent material and those using distinct modeling, and the consistent results prove the practicability and effectiveness of the presented method.
