| Abstract |
The residual stress distributions in a brass tube drawn by a fixed back-tapered plug method have been measured by a material stripping method. The measured data are comparable with the results calculated by the elasto-plastic finite element method. The residual stress distributions in brass tubes made by sinking, and fixed tapered, fixed cylindrical and fixed back-tapered plug methods have been calculated using the finite element method. The FEM results show the development of a compressive residual stress in the inner walls and a tensile stress in the other walls of the tubes produced by the sinking and fixed tapered plug method, whereas the nature of the stresses between the inner and outer walls were switched in case of the tube made by the fixed back-tapered plug method. The lowest residual stresses develop in the tube made by the fixed cylindrical plug method. |
