Abstract: Recent results (Khraisheh et al., 1995 and 1997) have indicated that superplastic materials exhibit a strong degree of anisotropy and that the plastic flow cannot be described by the isotropic ...

Abstract: Currently available models describing superplastic deformation are mostly based on uniaxial tensile test data and assume isotropic behavior, thus leading to limited predictive capabilities of ...

Abstract: The bulge forming performance of Pb-Sn superplastic sheet materials is evaluated under different forming pressure-time profiles. In addition, an “optimum” pressure-time profile based on variable ...

Abstract: This paper studies the effects of interfacial friction distribution on the integrity of superplastic formed parts. For that purpose, the deformation of AA5083 superplastic aluminum alloy into a ...
