本文藉由擴張史磋公式維度,設計相對應之邊界元素程式,解決二維磁電彈材料的孔洞、裂紋與界面等問題。並利用商用軟體Ansys與解析解佐以模擬與驗證。
另外,過去由於矩陣運算的便利性,因而採用以矩陣運算見長的MATLAB軟體來撰寫此邊界元素法,但又因邊界元素法需使用大量迴圈運算,使運算速度大幅拖慢。本研究以MATLAB軟體與FORTRAN軟體撰寫相同架構之邊界元素程式,客觀且公正的表現兩者於撰寫難度與迴圈運算速度的優劣比較。
By extending the dimension of Stroh formalism and using the associated boundary element, we can successfully solve two dimensional linear magneto-electro-elasticity defect problems. We also use commercial software and explicit solution to prove the correctness of our boundary element design.
In the past, because the powerful matrix operators of Matlab, it has been used to design the boundary element code. But, the massive number of loop slows down the computation process. In this paper, we use the computer language "Fortran" to rewrite the boundary element code under the same design structure and compare the computational efficiency of these two different computer languages.
