FEA analysis of thin steel sheet with different locations of reinforcing ribs created by local laser treatment

Abstract

The main purpose of the research was to determine the effect of local laser heating on the tensile stress under load. The simulation results show that the different locations and the number of laser tracks (internal reinforcing ribs) on a thin-sheet surface had a great influence on the stress distribution during tensile loads. The finite element analysis of equivalent Von-Mises stresses and stretching of thin-sheet steals acknowledge that the samples with the internal reinforcing ribs have a greater resistance to tensile load
