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(diǎn)技術(shù)，逐步釋放裂尖單元節(jié)點(diǎn)的方法來模擬裂紋的擴(kuò)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(jī)場的局部平均理論和一階泰勒展開得到了應(yīng)力強(qiáng)度因子均值和方差的計(jì)算公式。
