• One of the most important causes of steel profiles failures is the residual stress. They are those stresses that are locked in the object without the application of any service or external loads. They influence mechanical properties of structural material and as a consequence the propagation of cracks. In this paper we study the formation of the residual stress in the straightening process through a realistic numerical simulation.

  This is achieved using a 3D Finite Element Model (FEM) developed with ABAQUS®.
