Abstract Scope |
Steel is produced in a wide variety of types and shapes, each one efficiently serving one or more applications. The objective is to carry out an experimental study identifying the elastoplastic properties of SAE 1045 structural steel. Although the flow limit and rupture stress vary with the loading speed at high temperatures, the elastic properties are not significantly affected, which characterizes a elasto-viscoplastic behavior. In order to analyze the elasto-plastic behavior of these materials, tensile tests will be carried out to characterize the permanent deformation and the hardening. In the case of small deformations in the classic model of Lemaitre and Chaboche is suitable to describe the elasto-plastic behavior of these alloys at room temperature. A simple procedure for identifying all constants will be performed. The parameters that appear in the model proposed by Lemaitre-Chaboche will be identified experimentally |
