Abstract

Finite Element simulation of superplastic forming of Ti-6Al-4V sheet into a hemisphere is carried out using two different forming approaches. The first approach is based on a constant strain rate scheme. The second one is based on an optimum variable strain rate scheme developed using a combined micro-macro stability criterion. It is shown that the forming time can be significantly reduced without compromising the uniformity of thickness distribution when using the proposed optimum approach.
