摘要: 本文用Liapunov第二方法分析了周边受轴对称径向冲击载荷作用的极正交各向异性固支圆板的稳定性.分析是在小挠度和弹性范围内进行的.冲击载荷被假定具有阶梯脉冲形式.导出了相应的稳定性条件.

Abstract: Liapunov's 2nd method is applied to analyse the Stability of a ciamped poleorthotropic round plate acted by a radial axisymmetrical impact load on its periphery. The analysis is carried cut under the assumptions of small deflection and elasticity The impact load is supposed to have a step impulsive form. A sufficient stability condition is given.-
