本文嘗試以假設應變場進行結構分析,此法與傳統假設位移場的做法,或是平滑化有限元素法不同,為一全新的嘗試。
此法在解一維桿件時表現良好,有下列兩種優點(1)應變場可假設相對簡單的函數、(2)經由積分求得位移,其誤差比基本未知數應變更小
在嘗試二維平面問題時,目前仍無法獲得滿意的結果。
This paper attempts to solve the structural analysis with assumed strain field. This method is different from the traditional assumption of displacement field or the smooth finite element method. It is a brand new attempt.
This method performs well when solving one-dimensional member. There are two advantages of this method, first the strain field can use a relatively simple function like the linear function, second the error of displacement can be reduced by integration.
However, it can not get results of satisfaction when trying a two-dimensional plane problem so far.
