Analysis of the Elasto-Plastic Behavior of SAE 1045 Steel Submitted to Cyclic Loads

This work proposes an elasto-plastic study of SAE 1045 steel through a stress versus cyclic deformation curve, which was the basis for calculating the material's hardening parameters, defining the isotropic hardening value as null and kinematic hardening value as 415.05 MPa. Therefore, due to the wide use of SAE 1045 steel in structures and elements that undergo cyclical stresses, the parameters defined in the present work are highly relevant for the analysis of structures based on this material, making it easier to meet the needs during research, diagnostics, or sizing using this steel. The mathematical model used proved to be efficient in generating results compatible with those expected based on the bibliography.
