摘要：
Superplastic forming is a manufacturing process whereby certain materials under the correct conditions of temperature and strain rate exhibit high ductility and can be blow-formed into a die to produce components that are typically very light and strong. It is crucially important, in the process, to be able to control the pressure cycle in order to obtain the optimum strain rate. This paper considers methods for calculating the pressure cycle which may be incorporated into a finite element program for simulating the forming process.
