臺灣博碩士論文加值系統

本文考慮一異向彈性楔型體（Wedge）內含一差排的問題。首
先，利用以Stroh方法為基礎所發展出之對偶邊界積分方程式
（Dual Boundary Integral Equations），配合差排作用在無限
域之基本解，並使用Gauss積分方法得到方程式之數值解形式，計
算在楔型體邊界上的位移梯度（Displacement Gradient）；繼而
探討差排在楔型體內所受的應力狀況，並計算差排上之作用力
（Force of Dislocation）。所謂差排之作用力為一能量力
（Energetic Force），其定義為"因差排位置變動所造成系統自
由能變化之虛擬力"。
本文所建立之邊界積分方程式模式，不僅可分析等向性材料或
是正交性材料，還可以處理文獻上尚無之一般異向性內含差排之
問題。本文算例中，除和文獻中已有之結果比較，以驗證本文之
正確性，還有文獻上尚無之算例。

This text consider a dislocation on elasticity
anisotropic wedge question 。First ,to make use of Stroh
method base on development "Dual Boundary Integral Equation",
harmony with dislocation action on limitless region base
solution , moreover to use "Gauss Integration method "
obtain equation numerical solution form , compute in wedge
boundary displacement gradient ; to continue to probe
into dislocation in wedge interior to bear stress situation ,
moreover compute on force of dislocation。What is called
force of dislocation is energetic force, it a definition
is because dislocation position and cause system free
energy to change of image force。
This text establish of boundary integral equation
mold , not only can analysis isotropic materials or orthotropic
materials , but also deal with general dislocation on
elasticity anisotropic wedge question in documents。This
text example , besides reslut to compare and documents ,
according to this text of correct ,even more not have
example in documents。
