摘要

This study focuses on developing a theoretical formulation for fiber-reinforced composite materials at fiber-crack angles of 0 and 90°, utilizing the reinforcement isotropic solid model to determine the fracture parameters of the fracture process zone. The derived formulations are subsequently verified through experimental tests. Additionally, a new relationship is proposed to ascertain the fracture toughness of the damaged zone, considering the volume of damage. Comparative analysis of the effective fracture toughness at fiber-crack angles of 0 and 90° reveals that the composite exhibits enhanced resistance to crack propagation when the crack is oriented perpendicular to the fiber direction (90°), as compared to parallel orientation (0°).
