FEA analysis under bending loads of thin steel sheet plate with double side reinforcing ribs created by laser treatment

Abstract

The main goal of the study was to determine the effect of local laser treatment on bending stresses under load. The simulation results show that the different locations and number of laser tracks (internal rigidity ribs) on the thin-sheet surface had a influence on the stress distribution under bending loads. Finite element analysis of the equivalent von Mises stresses and bending of thin sheet steels confirms that specimens with internal stiffeners are more resistant to bending loading.
