Abstract
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.

为了给工程应用提供简便而有效的数值计算方法,提出了橡胶-帘线复合材料的一种非线性数值模型。首先推导了这种模型的有限元格式,以便在ABAQUS软件基础上实现这种模型;然后在单胞有限元分析的基础上,将此类超弹性基体、长纤维增强复合材料等效为一种横观各向同性超弹性材料。给出的数值算例将此方法的计算结果与纤维、基体分别细分单元的有限元分析结果进行了比较,验证了该方法的有效性与实用性。
