When the tensionin the top (created by shrinkage) has built up, it eventually releases - and it releases in the form of a crack.
由于收缩造成的面板张力不断累积，导致裂纹。

In addition, when there are tensioncrack and water in the slope, the critical inclination has relations with the position of crack and the level of water.
此外，当边坡中有张裂缝和水时，滑面的临界倾角还与张裂缝的深度和水位高度有关。

In this paper, boundary collocation method is used to calculate stress intensity factors of an eccentric crackin an elliptical disc subjected to a uniform tension stress.
