Based on the laminate theory, a laminate weakened by damage is treated as an anisotropic thin plate. Using the complex potential method in the plane theory of elasticity of an anisotropic body, the series solution of finite anisotropic thin plate containing an elliptical inclusion is proposed with the help of Faber series. A hybrid element with an elliptical inclusion for anisotropic materials is obtained by using the hybrid variable principle, and the element efficiency is verified by numerical examples. The state of the damage is modeled by an elliptical soft inclusion, and using the point stress criterion based on characteristic curve and Yamada-Sun etc. criteria, the prediction of the strength of a composite laminate with damage is set up. The effects of various parameters on the stress distribution and the residual strength of a composite laminate weakened by damage are detailedly studied.

首先基于经典层板理论，将复合材料层板的弹性问题化归为均匀各向异性板来求解；采用各向异性体平面弹性理论中的复势方法，以Faber级数为工具，给出了有限大含椭圆核各向异性板弹性问题的级数解形式；利用杂交变分原理，成功导出含椭圆核各向异性板杂交应力有限元，并用算例验证了该单元的可行性和有效性；采用含刚度折减椭圆形弹性核的冲击损伤模型，引入基于特征曲线和Yamada-Sun破坏准则的点应力判据，建立了含损伤复合材料层板剩余强度的分析方法；通过数值计算详细讨论了各种几何参数对损伤层板应力分布、剩余强度的影响，得到了一系列对工程应用具有实用价值的结论。

The theory and method of neural network,and the feasibility and superiority of building the coal bed geological model are also discussed by considering the geological variable characteristics,such as space territory,continuity,anisotropism and great non-liner relation.

摘 要：分析了建立矿床地质模型传统的估值方法的不足，针对地质变量之间具有空间局域性、连续性和各向异性，以及高度非线性关系的特征，阐述了应用人工神经网络原理和方法建立矿床地质模型的可能性和优越性，建立了地质变量参数估值计算的神经网络模型的基本结构，描述了地质变量与其影响因素之间的非线性映射关系，从而提出了基于人工神经网络原理的地质模型估值方法。
