Application of residual stress measurement method in analysis of vault defect on sheet metal surface
Abstract：Sheet metal often turns vaulted when its thickness is more than 0.35mm which happens in the production in one corporation, which makes the products unqualified. In order to find out the cause that leads to the default, residual stress on the surface of sheet metal after every working procedure is measured by the Hole-drilling Method. The results show that a certain working procedure makes much more residual stress and its distribution is asymmetric on sheet metal surface in sheet metal working process. That is the main reason to make sheet metal unqualified.
