复合材料层合圆柱壳的径向脉冲屈曲

针对无限长复合材料导合圆柱柱壳或圆环受均匀性向脉冲冲击作用下的动力屈曲，采用Ｌａｇｒａｎｇｅ方程导出包含横向剪为形和转动惯量的屈曲控制方程，由四阶Ｒｕｎｇｅ－Ｋｕｔｔａ方法所得的数值结果，寻找占优屈曲模态数及对应于允许初缺陷放大值时的临界冲击速度，通过算列，讨论了横向剪切变形，转动惯量，铺层角度等因素对角铺设层圆柱壳动力工的影响。

Radial Dynamic Pulse Buckling of Laminated Composite Cylindrical Shells

For a long laminated composite cylindrical shell subjected to uniform radial impulse, the pulse buckling equations including transverse shears and rotatory inertia are derived by using Lagrange equation. According to numerical results obtained by fourth order Runge Kutta method the number of most amplified mode and the critical velocity are presented. The effects of transverse shears, rotatory inertia and lamination angles on the dynamic buckling of angle ply cylindrical shells are discussed.
