Fiber Composite Structural Durability and Damage Tolerance: Simplified Predictive Methods

Source

Simplified predictive methods and models (“theory”) to evaluate fiber/polymermatrix composite material for determining structural durability and damage tolerance are described. This “theory” includes equations for: (1) fatigue and fracture of composites without and with defects; (2) impact resistance and residual strength after impact; (3) thermal fatigue; and (4) combined stress fatigue. Several examples are included to illustrate applications of the “theory” and to identify significant parameters and sensitivities. Comparisons with limited experimental data are made.
