摘要: 在足够大的压力作用下,层合板中的分层(delamination)会产生屈曲和后屈曲。本文分别用力法和位移法求解了受压固支正交异性矩形分层的屈曲和后屈曲问题,把一组非线性偏微分方程构成的边值问题化为求解一组非线性代数方程组,最后给出了有关的数值结果。

Abstract: The delaminaton in a laminate will induce buckling and postbuckling under a sufficiently large in-phane compression. The problems of buckling and postbuckling of clamped orthotropic rectangular delamination under compression have been solved by use of both force method and displacement-method in this paper. The solution of the boundary-valve problem of a set of nonlinear partial differential equations is reduced to solving a set of nonlinear algebriac equations. The corresponding numerical results are given.
