EFFECTIVE ENERGY DISSIPATION ANALYSIS METHOD FOR FATIGUE DAMAGE OF LAMINATED COMPOSITES

The irrecoverable process of energy dissipation is analyzed during the fatigue damage of the fiber-reinforced laminated composites. After thinking about the different loading sequence, a nonlinear fatigue cumulative damage rule, which is based on the effective hysteresis energy dissipation, is suggested. The present cumulative damage rule is able to correctly describe the loading order effect, about which a rigorous theoretical and experimental proof is provided.
