Considerations about Residual Stress Due to Stamping Process in Fatigue Life Prediction 2002-01-3523

Usually in Computer Aided Engineering (CAE) analyses, Computer Aided Design (CAD) data is meshed and analyzed with regard to displacements and stresses. So far, it is not common to account for residual stresses due to the manufacturing process in these analyses.
This work proposes a methodology based on simplified abaqus Standard/Explicit models to evaluate residual stresses due to stamping and bending manufacturing process in truck rails and suggests a methodology to use this residual stress data in truck frame CAE durability analysis making it possible to compare how different a predicted fatigue life can be when residual stresses are considered.
