Abstract
The presence of holes significantly influences crack growth in elastic–plastic materials under monotonic loading. This study investigates the effect of holes on crack propagation in SS304 by evaluating the -integral. A modified approach is developed to derive a geometry-dependent function for , while revised factors and improve the accuracy of for nonstandard geometries. Finite element simulations using configurational forces provide additional insights into the crack driving force. This study enhances predictive capabilities for crack growth behavior in engineering applications.
期刊介绍:
Theoretical and Applied Fracture Mechanics'' aims & scopes have been re-designed to cover both the theoretical, applied, and numerical aspects associated with those cracking related phenomena taking place, at a micro-, meso-, and macroscopic level, in materials/components/structures of any kind.
The journal aims to cover the cracking/mechanical behaviour of materials/components/structures in those situations involving both time-independent and time-dependent system of external forces/moments (such as, for instance, quasi-static, impulsive, impact, blasting, creep, contact, and fatigue loading). Since, under the above circumstances, the mechanical behaviour of cracked materials/components/structures is also affected by the environmental conditions, the journal would consider also those theoretical/experimental research works investigating the effect of external variables such as, for instance, the effect of corrosive environments as well as of high/low-temperature.
