Abstract: A composite low-cycle fatigue analysis model, which can forecast delamination fatigue life of laminates, is created based on VCCT. Low-cycle fatigue of delamination growth is analyzed by ABAQUS with the method of direct cyclic approach, by first defining the interface through delamination, and the fracture energy release rates at the crack tips in the interface. Elements are calculated based on VCCT technique, and the onset and delamination growth are characterized using the Paris law.

Key words: VCCT, composite, low-cycle fatigue
