| 摘 要： | 取样条函数作为挠度试函数,运用加权残值法求得初缺陷矩形薄板动力屈曲的控制方程,采用四阶Runge-Kutta法求解该控制方程,并用Fortran语言编制了相应的计算程序。构造的B样条函数能适应板侧边上的任意弹性转动约束,讨论了初始几何缺陷、冲击载荷持续时间和弹性约束的影响。

| Abstract: | The spline function is chosen to describe the deflection.The governing equations of the dynamic buckling of imperfect rectangular plates are obtained by weighted residual method.The equations are solved by a fourth-order Runge-Kutta method,and the computational code is developed in FORTRAN.The formed B- spline function is adaptable to any elastic restraints against rotation.The influences of initial geometric imper- fection,load duration and elastic restraints are discussed. |
