Numerical simulation of sheet metal multi-point stretch forming and compensation of die surface;

The multi-point stretch forming process of spherical surface parts of aluminum alloy sheet metal with conventional clamp mode and the flexible clamp mode with different transition region were simulated by an explicit finite element software.

Multi-point stretch forming is a new sheet metal forming technology.
