But this partial differential equation can not be directly integral, so usually use Navier method, Rayleigh Ritz method and finite difference method and other methods.
但这一偏微分方程不能直接积分,所以通常用纳维法、瑞利-里兹法、有限差分方法等方法求解。
The convergence of Ritz method based on the principle of minimum potential energy is discussed.
本文讨论了基于最小势能原理的里兹法的收敛性。
This article adopted Ritz method and divide-fit mathematical method, solved the problem of elastic buckling of thin plate under compression and bend multiplicity action.
采用里兹法和切分拟合的数学方法,讨论了单向压缩和弯曲共同作用的薄板弹性屈曲问题。
