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.
在梁的中線上採用雙重節(jié)點技術，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.
