  剪切变形理论
     Based on the first-order shearing deformation theory, nonlinear dynamic governing equation of laminated composite shallow spherical shells under uniform load are built and solved by Galerkin method and Runge-Kutta method. Budiansky-Roth motion criterion expressed by the displacement of the peak of the shell is employed to determine the critical impact buckling load. The influences of physical parameter and geometric parameters on impact buckling are discussed as well.

The solution of differential equations' MWR is approached in this paper. It is proved that the minimum of the square functional Ⅰ of this method is existent. Then, the shear deformation theory of cylindrical shells is established. By using the method in examples, the precision of the shear deformation theory of cylindrical shells is analysed (its fundamental relations contain five second-order partial differential equations of two variables). The results show that the solution of differential equations' MWR is successful, and the precision of the shear deformation theory of cylindrical shells is satisfactory.

This paper investigates the application of Dynamic-Relaxatio:n(DR)method to the problems of nonlinear bending of rectangular plates laminated of bimodular composite materials.

本文探讨了动力松弛(DR)法在双模量复合材料叠层矩形板非线性弯曲问题中的应用。在分析中分别采用叠层板大挠度经典理论和计及大转动(在Von Karman意义上)的复合材料叠层板剪切变形理论。 我们发现,对于考虑横向剪切变形的非线性弯曲问题,如何计算虚拟密度以控制数值计算的稳定性,仍然需要进一步研究。本文提出了一种虚拟密度的计算方法,从而保证了本课题数值计算的稳定性。 文中介绍了用DR法求解双模量复合材料叠层板非线性弯曲的主要步骤,给出了由轻度双模量材料(Born-Epxy(B-E))和高度双模量材料(Aramid-Rubber(A-R)和Polyester-Rubber(P-R))的两层正交叠层简支矩形板在正弦分布载荷及均布载荷作用下的非线性弯曲特性的数值结果。将所得结果和小挠度分析结果及普通复合材料的结果作了比较,并分析了横向剪切变形对无量纲中心挠度的影响。

In this paper,the starting point is the equations of motion in terms of the displacement variables for the heterogeneous anisotropic plates developed by J. M. Whitney. It is shown that, by introducing the function of displacement function φ(x,y,t) the system of original differential equa-tions in REFERENCE [1] for the first-order shear deformation theory of symmetric cross-ply laminated plates can be transformed into a single differ-ential eqution of displacement function,and on the basis of such a differential...

In this paper,the starting point is the equations of motion in terms of the displacement variables for the heterogeneous anisotropic plates developed by J. M. Whitney. It is shown that, by introducing the function of displacement function φ(x,y,t) the system of original differential equa-tions in REFERENCE [1] for the first-order shear deformation theory of symmetric cross-ply laminated plates can be transformed into a single differ-ential eqution of displacement function,and on the basis of such a differential eqution an exact solution is given to the problem of free vibration of symmetric cross-ply laminated plates including various boundary conditions. The example shows that the influence of various boundary conditions obviously exist,and the natural frequencies obtained by the analytical method proposed in this paper arc lower than those of calculated results by using the approximate methods.
