finite difference method

有限差分法

本文結合上界限法(upper bound method)、有限差分法(Finite Difference Method)及變分法(Variational),來作為分析圓盤熱鍛粗問題的工具. 首先藉由流函數所定義呈函數形態的動可容速度場及變形場,建立圓盤鍛粗加工所需的上界限能量消秏的總功率,其次再以有限...

finite difference method

差分法

热物性质仅为温度函数;假设塑件为薄件(厚度与长/宽度比超过1:10),因此可用可压缩的GHS(Compressible数值解法采用混合有限元素法(Finite Element Method)与差分法(Finite Difference Method)分别求解流动平面方向与厚度方向变量.
