Abstract (EN): Cohesive zone modelling (CZM) has been extensively considered as a powerful method for analysis of initiation and propagation of delamination in composite laminates subjected to cyclic loading. By making a relation between the damage parameter and the loading cycles, damage accumulation can be calculated, and the fatigue life of a component can be estimated. The aim of the current research is to present a new fatigue damage accumulation (FDA) model. The proposed model is developed based on the concepts of CZM and by linking the fracture mechanics to damage mechanics approaches. For this purpose, a developed user material subroutine (USDFLD) is implemented in a finite element software to simulate the initiation and propagation of damage in an interface layer of a composite material subjected to cyclic loading. The method is validated for different loading conditions using Paris law results. Good agreement between the proposed method and the Paris law results is observed.
