crack-tip element

基本解釋

The concrete beam model is meshed using a method without need of considering the crack-tip singular element.
在梁的中線上采用雙重節(jié)點技術(shù)，逐步釋放裂尖單元節(jié)點的方法來模擬裂紋的擴展。
The stiffness matrix of a hybrid crack-tip singular element is first derived, then by use of first-order Taylor expansion the mean and variance of stress intensity factors are formulated.
文中首先給出了雜交模式的裂紋尖端奇異單元的剛度矩陣，然后基于隨機場的局部平均理論和一階泰勒展開得到了應力強度因子均值和方差的計算公式。
