Hydro forming of high purity copper sheet to produce different shapes

Abstract EN

-The 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.
