摘要：

For the analysis of plastic flow and necking development of materials with both work hardening and strain-rate sensitivity under uniaxial tension, it is shown that the basis of E. W. Hart's analysis is same as that of the analysis of J. W. Hutchinson et al based on the constitutive law. Then, on the basis of Hart's analysis, the flow-stability and the criterion of stability of Hart and J. J. Jonas et al are discussed. Considering the initial geometric imperfection ( alpha (0)), the incremental analysis and the integral analysis are given for the necking development.
