An investigation of springback stresses in AISI-1010 deep drawn cups
The residual stresses created by deep drawing of AISI-1010 cups were investigated by means of neutron diffraction. The wall thickness of the cups was below 3.0 mm, for which 8–10 through-thickness measurements were conducted. It was found that the axial, and tangential stress profiles are similar to what is expected from a bending–unbending operation, but it also exhibits a strong dependence on...
متن کاملA synchrotron study of residual stresses in a Al6022 deep drawn cup
Fueled by pressures to reduce scrap and tooling costs, the modeling and prediction of springback has become a major focus of interest in sheet metal forming. Finite element codes and packages are being developed or improved but face the demand for higher predictive accuracy which, in turn, requires accurate property data and a more complete understanding of the stresses that are responsible for...
متن کاملAnalysis of the Residual Stresses Distribution in the Case of Drawn Parts Made from Steel Sheets
The residual stresses that occur in the machined parts after the tools removing are the main cause that determines the springback of the draw parts made from metal sheets. Hence, to investigate this instability phenomenon it must be known the state of residual stresses developed in the part by its machining. But, the experimental investigation of the residual stress distribution in the case of ...
متن کاملResidual Stresses Measurement in Hollow Samples Using Contour Method
Residual stresses are created usually undesirably during manufacturing processes, including casting, welding, metal forming, etc. Residual stresses alone or in combination with other factors can cause the destruction and fracture of components or significant decline in their service life. Therefore, it is crucial to measure the residual stresses. Contour method is a destructive testing method c...
متن کاملRevision Residual Stresses in Oscillating Thoracic Arteries Reduce Circumferential Stresses and Stress Gradients Residual Stresses in Oscillating Thoracic Arteries Reduce Circumferential Stresses and Stress Gradients
The purpose of this paper is to examine the eeects of residual stresses and strains in the oscillating arteries on the stress distribution in the vascular wall. We employ a static theory of large elastic deformations for orthotropic material (Chuong and Fung, 1986) with the acceleration term added to make the theory dynamic. We use the static elastic parameters of residual stresses in our analy...
