crack-tip element

基本解释

The concrete beam model is meshed using a method without need of considering the crack-tip singular element.
在梁的中线上采用双重节点技术，逐步释放裂尖单元节点的方法来模拟裂纹的扩展。
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.
文中首先给出了杂交模式的裂纹尖端奇异单元的刚度矩阵，然后基于随机场的局部平均理论和一阶泰勒展开得到了应力强度因子均值和方差的计算公式。
