Progressive Fatigue

View the theory and technical details of our approach to predicting composite fatigue life for unidirectional and woven polymer reinforced composite materials.

In the first section we outline the phenomenology of composite fatigue, discuss how composite fatigue differs from metal fatigue, and qualitatively describe the unique approach for predicting composite fatigue life.

The remaining sections outline the theoretical framework for the kinetic theory of fracture, linking microscopic damage with macroscopic failure, modeling the consequences of fatigue failure, and finally the material characterization process required to use the fatigue models.
