摘要: Abstract An analytical model to predict bearing failure of pinned-joint composite laminates is proposed. The combines a mass-spring reproduce the joint stiffness and characteristic curve damage. When was verified at any ply, corresponding spring element removed from model. accuracy validated through comparison with experimental results. Analytical predictions agreed load–displacement curves ultrasonic inspections tests. present predicted different stages in failure, considering consecutive plies.
