自從移動式最小平方法(moving least-square,MLS)問世以來,許多新的數值方法也依循MLS而產生,然以此法為基礎的數值方法往往需要將其形狀函數(shape function)微分,而類似的微分過程通常需要繁雜之計算量,本文研究之微分再生核近似法(differential reproducing kernel approximate methods,DRKM)是一種可以簡便計算形狀函數微分,且不失計算精確度的方法。文中將由移動式最小平方法(MLS)為基礎,加上再生核法(reproducing kernel methods,KRM)理論,發展出移動式最小平方再生核法(moving least-square reproducing kernel methods,M L-S RKM),再經由M L-S RKM在微分上的便利性推導出DRKM理論,最後根據彈性力學理論,從三維彈性力學方程式出發推導三維問題控制方程式與邊界條件,經由DRKM理論加上三維彈性力學控制方程式與邊界條件,來建立解析問題的程序。並且利用DRKM來處理三維彈性力學扭轉問題,以探討此法在數值分析上之可行性。
