） Abstract： Superplastic materials are sensitive to strain rate sensitivity
There are different comments on constitutive equation, instable criterion, prediction of limit strain and failure strain in study of macro-mechanics of superplastic materials
In order to investigate deeply the changing law of strain rate during deformation, it is necessary to normalize and unify those differences
In this paper, samples of superplastic tensile deformations are regarded as nonlinear dynamical system
Through establishing nonlinear differential equation and studying the changing law of strain rate, strain-rate fluctuation model for superplastic tensile deforming and constitutive equation under different deformation path are given
Keywords： Superplastic deformation, strain rate, constitutive equation, instability, differential equstion 下载PDF阅读器 PDF全文下载： 初稿 （ 199 ） 作者简介： 通信联系人： 【收录情况】 中国科技论文在线： 索忠林
