Numerical modeling of dynamic crack propagation mechanisms using a moving mesh technique based on the ALE formulation

Abstract. This work proposes a new FE model to predict dynamic crack propagation mechanisms in quasi-brittle materials. The numerical strategy uses Moving Mesh (MM) technique consistent with the Arbitrary Lagrangian-Eulerian (ALE) formulation reproduce variation of geometry computational domain caused by dynamically growing cracks. Specifically, motion mesh nodes takes place consistently conditions dictated classic Fracture Mechanics, which provide concerning direction and velocity advancing As remarkable key novelty, proposed method introduces ALE M-integral for extracting Dynamic Stress Intensity Factors (DSIFs) at moving front. allows fracture variables on deforming elements without losing accuracy. Comparisons analytical data are assess validity efficiency strategy.
