Experimental Validation of Residual Stress Simulations in Welded Steel Tubes with Digital Image Correlation KU Leuven
As each production process introduces residual stresses in the material, cold-rolled steel tubes are not delivered stress-free. The motivation of this research can be traced back to the laser cutting of tubes. During the cutting process, residual stresses are relieved, which causes deformation of the tube and a reduction of the precision of cut. Residual stresses also play a role in stress corrosion and sudden collapse of tubular ...
