Thirdly, from the idea of locally linear approximate, another tangent - plane algorithm is presented for the distance between the convex nurbs surfaces. the critical step is the construction of the support mapping by gjk and lc to search for nearest points, and emphases are laid on dealing with isotropic cases and choosing initial iterated points. it is also proved that no isotropism during iteration would take place if initial iterated points are positive points
切平面法是運用gjk和lc構造支撐映射的原理而設計的一個搜索近點對的迭代法，著重給出了迷向情況的處理和初始迭代點的選取方法，並證明了只要將初始迭代點取為陽點，就不會出現迷向情況。 -
At the transition point the dynamical fluctuations are anisotropic in the longitudinal - transverse planes and isotropic in the transverse plane
在轉變點外，動力學起伏在橫平面各向同性，在縱-橫平面各向異性。 -
The main results and academic contributions of the dissertation can be summarized as following : 1 ) for the difficulty to obtain the accurate analytical solution of the stress constraints around 3d cracks, detailed 3d fe analyses have been conducted to study the out - of - plane constraint factor tz around a straight through - thickness crack, a quarter - elliptical corner crack and a semi - elliptical crack embedded in an isotropic elastic plate subjected to uniform remote tension loading. the distributions of tz are minutely studied in the forward section of the cracks. strong 3d zones ( tz > 0 ) along the crack front were investigated despite the far field stress - free boundary conditions
全文主要研究內容和學術貢獻如下: 1 .針對一般三維裂紋端部場應力約束準確解析的困難，對均勻拉伸載荷作用下各向同性彈性板中穿透厚度中心直裂紋、半橢圓表面裂紋和1 / 4橢圓角裂紋進行了大量詳細的全場應力三維有限元分析，首次全面分析了非穿透裂紋端部場三維影響區范圍，給出了不同形狀三維裂紋前沿離面應力約束因子tz的數值解，並結合k場平面解給出了非穿透裂紋端部應力場k - tz雙參數描述。 -
Abstract : the anti - plane problem in transversely isotropic magnetoelectroelastic materials containing an elliptic inclusion is considered by using the complex variable approaches. the analytical expressions for the field variables in both the matrix and the inclusion are obtained when the stresses and the electromagnetic fields at infinity are uniform. the results show that the stress, the electric displacement and the magnetic induction inside the inclusion are constants
文摘:用復變量方法研究了橫觀各向同性電磁彈性固體的反平面夾雜問題，得到了遠場均勻應力和電磁場作用下夾雜內外彈性場和電磁場的解析表達式，結果表明夾雜內的應力、電位移和磁感應強度為常量。
