The concurrent ratcheting and stiffness degradation-based damage variable in SA508 steel samples undergoing stress cycles at room and elevated temperatures

This study evaluates the interaction between ratcheting and stiffness degradation in SA508 steel samples at various operating temperatures using a combined isotropic-kinematic hardening framework. The Ahmadzadeh-Varvani (A-V) kinematic hardening rule, along with the isotropic hardening description b...
