| 摘 要： | 本文基于相同边界条件下铺层构成对失稳后的变形形态影响不大的基本假设,根据理论和实践经验得到的准最佳铺层失稳后的位移场为基础,给出了确定最佳铺层参数的工程方法。计算表明,其基本假设和解题思路是正确的。由于本方法最后归结为解一个一元三次方程,使计算大为简化,可降低设计成本和周期,在工程设计中具有实际意义。

| Abstract: | Based on a basic assumption that the effects of lamina situation on deformation mode under postbockling conditions is very small and by use of the displacement field of quisi-optimal lamina obtained by theory and experience, a engineering approaximate method determining optimal lamina parameters is given.The results show that the basic assumption and the method persented in this paper are right.As only one three-degree equation with one variable is to be solved in this method, the calculation is simplified significantly, and design cost and cycle can be redued ,so that the method will play an important part in engineering design. |
