A novel approach of residual stress prediction in ST-14/ST-44 laser welded blanks; mechanical characterization and experimental validation
Source abstract
Abstract
Abstract Sheet metal components capitalizing on the advantages of laser-welded blanks (LWBs) are widely used in automotive industries. In the current study, residual stresses are estimated in a deep drawing process of LWBs both experimentally (hole drilling) and numerically (using SIMUFACT™ and ABAQUS™). This study aims at predicting residual stresses during laser welding and forming processes to improve the quality and service life of LWBs. Validating our proposed model on automobile parts presents promising results in which welding geometry and residual stress of LWBs are well estimated. These numerical and experimental stress analyses agree with a maximum error of 6%.
