| 摘 要： | 用幂函数做试函数,用加权残值法中的配点法得出非线性方程组。用牛顿迭代法解得了夹层圆板在均布荷载作用下的非线性弯曲挠度和应力解。结果证明本方法具有计算精确,荷载收敛范围大的特点。

| Abstract: | In this paper,power functions have been taken as trial functions.The nonlinear functions are got through the method of point collocation.The results of stresses and deflections on sandwich plate are gained by Newton iteration method.They testify that the method has advantage of high accuracy and broad loads convergence. |
