| Abstract: | Liapunov's Znd method is applied to analyst the stability of a clamped poleorthotropic round plate acted by a radial axisymmetrical impact load on its periphery. The analysis is carried out 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. |
