摘      要：This study proposes a material constitutive model using a memory surface concept to accurately replicate the cyclic hardening and softening behaviors of SN490B structural steel under constant strain amplitude loading. The model combines isotropic and kinematic hardening rules, accounting for strain amplitude dependency in both hardening rules. The isotropic hardening rule includes hardening and softening mechanisms, enabling the accurate reproduction of cyclic hardening and softening behaviors dependent on strain amplitude. This approach successfully replicates the stress–strain relationship of the tested material. © 2024 Architectural Institute of Japan. All rights reserved.
