Finite Element Shot Peening Simulation For Residual Stress. Analysis And Comparison With Experimental Results

Abstract

This study was performed using the Finite Element Method with the main objective of simulating the shot peening process to evaluate the residual stresses. Shot peening was simulated considering the one single shot impact against a plate throughout an axisymmetric model. An integration explicit dynamic algorithm was employed, taking into consideration the elastic plastic behavior of the two bodies in contact. Slidelines were utilized to simulate the impact zone. The obtained results were compared with values of experimental expressions found in specialized literature. The finite element professional software denominated LUSAS(R) was used in the simulation.
