Abstract

This study explores the influence of in-plane constraint on the creep crack behavior of a new variant of SS316LN with 0.07% nitrogen under stationary and growing cracks through experimental and numerical approaches. The

Q

parameter is calculated to characterize the in-plane constraint, while the

C^{*}

parameter is used to analyze creep deformation and fracture behavior. Comprehensive experimental tests and finite element simulations provide insights into the interaction between in-plane constraints and crack-tip stress fields. The results enhance the understanding of constraint effects in stationary crack scenarios, contributing to the development of improved methodologies for high-temperature failure assessments and life prediction of structural components made of SS316LN.

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.
