Hydroforming of High Purity Copper Sheet To Produce Different Shapes
Engineering and Technology Journal,
2010, Volume 28, Issue 23, Pages 6634-6641
AbstractThe present research is focused on experimental results and theoretical
analysis of sheet hydronning of high purity copper with circular and square shapes under the biaxial stresses. It has been found that the displacement in the circular shape specimens is more than of the square shape specimens at the same area of deformation. However, at the same time. The plastic deformation equivalent at the specimens for the circular shape is more than of the square shape specimens at the same strain equivalent. The thinning of the sheets at the pole for the circular shape specimens is less than that of the square shape
specimens. This will lead to improve the performance of the circular shape product.
