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。

Stability analysis of Sanjiaoping slope under diverse work condition indicates that the result of strength reduction method is approximate to classical limit equilibrium method. The shape and the position of sliding surface are similar. So, the suggested method is rational.

通过对三交坪边坡不同工况下的稳定性分析表明，强度折减所确定的边坡安全系数与传统极限平衡法所得的结果十分接近，滑面的形状及位置也极为相似，因此认为该方法是合理可行的。

Every possible man was drawn up on this Sunday morning on the maindeck, not merely the two watches, but every 'idler' who had no place in the watches — the holders, who did their work so far below decks that for some of them it was literally true that they did not see the sun from one week's end to another, the cooper and his mates, the armourer and his mates, sail maker and cook and stewards, all in their best clothes with the officers with their cocked hats and swords beside their divisions.

在这个周日的早晨，每一个可能的人员都被叫到主甲板上，不仅仅是两班轮值，也包括不安排轮值的每个"闲散人员"——底舱，他们在甲板下的深处干活，以至于有些人真正是几周都看不到太阳。桶匠、军械士、制帆士、厨师、乘务，所有的人都穿着最好的衣服，军官们带着折起的帽子和佩剑站在他们分管部门的人员旁边。
