Crack growth modeling and simulation of a peridynamic fatigue model based on numerical and analytical solution approaches

Fatigue crack growth assessment of 2024-T3 aluminum alloy is carried out on the basis a recently developed peridynamic fatigue model. The governing remaining-life equation model has been solved by two different approaches i.e. numerical and analytical to perform fatigue-crack simulations for specimen with pre-existing crack. Remaining-life parameters solution are determined calibrating experimental data. predictions, associated material deformation under various loading conditions simulated approaches. Predicted results show that approach shortcomings in accurate predictions rates application conditions, while can be applied wide range good prediction accuracy stable growing Furthermore, it found computational time considerably shorter comparison approach.
