Finite element modelling of damage in superplastic forming of a titanium alloy
(Springer Verlag, 2009-12-15)This paper describes the application of a continuum damage mechanics methodology to the prediction of failure during superplastic forming of Ti-6Al-4V. A power law constitutive relationship is employed within a geometrically ... -
Finite element prediction of creep-plastic ratchetting and low cycle creep-fatigue for a large SPF tool
(Springer Verlag, 2010-03-03)Industrial experience shows that large superplastic forming (SPF) tools suffer from distortion due to thermal cycling, which apparently causes high temperature creep and plasticity. In addition to distortion, thermomechanical ...
