It is necessary to perform structure buckling load interval analysis because the uncertainty of structural own parameters should be considered. Critical buckling load of supercavitating projectiles is calculated by Galerkin method. The partial matrixes of critical buckling load implicit function to each uncertainty variable are deduced  and the interval of structure critical buckling load is calculated by interval analysis and convex model methods. Numerical results show that the nominal value  lower and upper bounds of critical buckling load increase with the increment of the ratio of base diameter to cavitator diameter. And the uncertainty degree of basic variables should be controlled as far as possible in the project for high reliability. 2011 IEEE.   Material properties test and numerical simulation of impact for die cast magnesium alloy (EI CONFERENCE) 会议论文  OAI收割 International Conference on Magnesium - Science, Technology and Applications, September 20, 2004 - September 24, 2004, Beijing, China Zeng X.; Wu Q.; Liyuan; Fan J. 收藏  |  浏览/下载：69/0  |  提交时间：2013/03/25 The poison's ratio of plane plate samples taken from AM60 magnesium alloy was tested in this paper. A number of strain controlled fatigue experiments were also carried out on MTS to investigate the stress-strain behavior under different temperature conditions. The finite element analysis software ANSYS was employed to simulate impact process of shot blasting. Results indicated that at the specific temperature condition the residual stress and plastic strain increased with impact velocity increasing. At the specific impact velocity  residual stress reduced and plastic strain increased with temperature increment.
