摘要
本文利用打靶法讨论了弹性基础上组合环形板在任意边界条件下受面内径向压力作用时的轴对称失稳.计算了临界荷载,并数值地研究了材料参数和几何参数对临界荷载的影响.
By means of the shooting method.the axisymmetrical instabilityof composite annular plates on an elastic foundation is investigated.The plate is subjected to a uniform in-plane pressure at the outer edgeand possesses any boundary conditions in the transverse direction of theplate.Critical loads are computed and the effect of material parametersand geometry parameters on critical loads is studied numerically.
