Cyclic Hardening Rule for Structural Steels with Yield Plateau
Publication: Journal of Engineering Mechanics
Volume 125, Issue 12
Abstract
The integral description of the back stress evolution model is extended to describe the behavior of structural steels with a yield plateau. For this purpose a new concept of the yield plateau region is introduced. The memory of maximal prestress, loading amplitude sensitivity, and hysteresis shape evolution are incorporated into the model. The proposed material description is applied to simulate the deformation response of structural steel st52 for a variety of uniaxial loading programs. Predicted results are compared with experimental observations.
