Abstract
The representative volume element (RVE) method is a common numerical modeling method for predicting the material properties of short fiber reinforced composites. The RVE generation efficiency is an important factor affecting the efficiency of the property prediction. For the problem of too many Boolean operation times which cause low efficiency of Boolean operation when the existing random sequential adsorption (RSA) method is used to generate RVE, the centroid distance calculations between the lasted randomly generated fibers and the existing fibers are introduced. Using the centroid distance, some randomly generated fibers, which are intersecting with the existing fibers, are filtered out to reduce the number of Boolean operations. And a filter based random sequential adsorption (FRSA) method for modeling RVE is presented. By comparing the number of Boolean operations and the time cost for generating RVE, the FRSA method has been verified, and the verification is performed with different RVE parameters and method parameters using improved FRSA method and Boolean operation based random sequential adsorption (BORSA).
