本研究探討彈性波在薄板內的計算。主要工具為邊界元素法並以其相關數值方法作為計算的基礎。
考慮的問題為透過計算描述具自由表面彈性薄板於一點受對稱表面應力時.其餘點從暫態到震盪的位移變化。主要目的為:
1.計算薄板內各點的位移作為進一步研究的工具
2. 提升運算效率以處理更複雜的情況
本研究引入OpenMP 的平行計算並達成顯著的效率提升.使原本用於短時間暫態的計算方法可以涵蓋更複雜的問題或更長的時間。
This paper considers an elastic thin plate with free surface subject to a symmetric sinusoidal loading. Boundary element method (BEM) and numerical methods developed in is used to compute transient waves
The main purposes are to:
1.Compute the displacement of elastic waves in a thin plate which can be used for further study
2.Improve computation efficiency to cover a wider range of problems
This paper incorporates OpenMP, an industrial application interface for parallel computing, to the programming. The work done here then extends existing codebase to handle computation-heavier problems.
