Influence of thermoelastic boundary conditions on the mechanical strength of cold-rolled silicon steels

Abstract

A numerical and experimental framework is proposed for an uncoupled thermoelastic analysis of anisotropic cold-rolled steel alloys Fe-3%Si to explore the influence on the material strength when subjected to thermal and inertial loads. Following the stationary thermoelasticity formulation of the boundary element method (BEM), this model focuses on the 2D study of these materials when the elastic properties are temperature-dependent and inertial forces are considerable. Validations and an industrial application are shown to illustrate the feasibility of using the framework proposed here to study the thermomechanical behavior of the Fe-3%Si, taking into account the influence of temperature on its mechanical and thermal properties. Finally, a complete database is provided for reproducibility purposes.
