Abstract

Summary: To simulate the deformation and the fracture of gradual multi‐fiber‐reinforced polymer matrix composites, a numerical simulation method for the mesoscopic mechanical behaviors was developed on the basis of the finite element and the Monte Carlo methods. The results indicate that the strength of a composite increases if the variability of statistical fiber strengths is decreased.
