The sequential static fatigue algorithm: a fast approach to predict composites delamination growth under fatigue loadings

Abstract

Delamination is among the most common and dangerous forms of damage in composite laminates [1]. Considering the widespread use of these materials in industrial sectors like aeronautics or automotive, predicting their propagation under fatigue loads is of extreme importance. Cohesive Zone Models (CZMs) and Virtual Crack Closure Techniques (VCCT) are generally the most adopted techniques for this purpose
