China ' s current beer trademarks are mainly divided into three types : one is the ellipse resembling qingdao beer trademark, the second is to stress local features like the great wall of tianjin, temple of heaven of beijing, guilin landscape, etc. the majority of them take places of interest, beautiful sceneries as the subject ; the third is the use of some foreign beer trademarks in joint ventures
我國現在啤標大約有三種類型：一是仿青島啤酒的橢圓形；二是突出地方色彩的啤標，如天津的長城、北京的天壇、桂林山水等，多以名勝古跡、秀水靈川作為題材；三是合資浪潮下一些外國啤酒商標的使用。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
首先基於經典層板理論，將復合材料層板的彈性問題化歸為均勻各向異性板來求解；採用各向異性體平面彈性理論中的復勢方法，以faber級數為工具，給出了有限大含橢圓核各向異性板彈性問題的級數解形式；利用雜交變分原理，成功導出含橢圓核各向異性板雜交應力有限元，並用算例驗證了該單元的可行性和有效性；採用含剛度折減橢圓形彈性核的沖擊損傷模型，引入基於特徵曲線和yamada - sun破壞準則的點應力判據，建立了含損傷復合材料層板剩餘強度的分析方法；通過數值計算詳細討論了各種幾何參數對損傷層板應力分佈、剩餘強度的影響，得到了一系列對工程應用具有實用價值的結論。
