1 A New Vision to Fatigue Fracture Modelling of Composite Materials via Employing the Phase Field Numerical Technique 1 The phase field method is shown to be effective in modeling fatigue fractures in composite materials in this commentary. By simulating crack initiation and propagation naturally, it captures complex microstructural interactions. It enhances fatigue life predictions by integrating statistical models, making it valuable for optimizing advanced composite materials. 1 2 Saeid Sahmani Department of Civil Engineering, School of Science and Technology, The University of Georgia Georgia s.sahmani@ug.edu.ge Fatigue fracture Composite materials Phase field method Cyclic loading Article1.pdf REFERENCES [1]Cui, H.; Du, C.; Zhang, H.
