MS306 - Computational Approaches To Fatigue Crack Growth

Organized by: L. Greco (University of Pavia, Italy), A. Patton (University of Bundeswehr, Germany) and L. Radtke (University of Rostock, Germany)
Keywords: Damage modeling, Fatigue crack initiation, Fracture mechanics
Fracture initiation and propagation remain central challenges in engineering, with significant implications across mechanical, civil, naval, aerospace, and other disciplines. Over the years, extensive attention has been given to the modeling of brittle [1] and ductile fracture to describe the ultimate behavior of materials. More recently, increased focus has been directed toward the initiation and growth of cracks under fatigue loading conditions. From a computational standpoint, modeling fatigue crack propagation offers the potential to significantly reduce the need for extensive laboratory testing, which is often time-consuming and complex. However, a key challenge lies in the simulation of a large number of load cycles required to accurately capture fatigue behavior. The aim of this mini-symposium is to bridge the gap between fatigue fracture research and computational fracture mechanics. It invites contributions on numerical models capable of capturing fatigue-driven crack evolution, including but not limited to phase-field methods [2] and peridynamics. Both academic and industrial applications are welcome. REFERENCES [1] Griffith, Alan Arnold. "VI. The phenomena of rupture and flow in solids."
