Abstract:

Numerical modeling has proved to be a powerful tool for development of hydroforming processes. There have been used various numerical models but it has been difficult to choose a model which would be good enough for a specific application. Both 3D-shell and 3D-solid models for numerical modeling of hydroforming of copper X-shapes are presented in this paper. The results of calculations have been compared with the results of experiments. Numerical models have provided quite high accuracy in getting the X-shape geometry for various process parameters. However, only 3D-solid model has been useful to analyze thickness distribution in X-shapes. What more, 3D-solid model has shown better results on load history.
