Damage Development Mechanisms in Notched Graphite Epoxy Composite Laminates during Compressive Fatigue Loading

摘要

This study has investigated the damage development mechanisms in notched graphite epoxy composite laminates during constant amplitude compressive fatigue loading. Laminates of two different stacking sequences were tested. The effect of the center notch on local stress-strain behavior during static loading, and the relationship between fatigue damage and the resulting life, stiffness, and strength of the laminates have been observed.
