A New Vision to Fatigue Fracture Modelling of Composite Materials via Employing the Phase Field Numerical Technique

Abstract

In recent years, fatigue fracture in composite materials has gained a great deal of attention, particularly with the advent of advanced numerical techniques such as the phase field method. It is particularly capable of simulating the complex behavior of fatigue fractures, making it a promising avenue for both researchers and engineers. A phase field method provides an accurate model of fatigue behavior of composite materials subject to cyclic loading by incorporating crack initiation and propagation naturally without the need for additional fracture criteria. As a result of the phase field method, cracks are represented as continuous variables rather than discrete entities due to the concept of a diffuse interface. The interaction between different phases in composite materials can cause intricate fracture behavior because of this characteristic.
