The study indicate that the surface form has no effect on kl, but has obvious effect on kll, and will affect the breaking angle and mode ; in finite plate, the boundary condition has effect on the sif and the k is bigger than in infinite plate ; the effect of the distance and the angle between cracks are all have obvious effects on the multiple crack interaction, and the interactions between cracks also have obvious effects on the sif, which can be neglect only when the distance is bigger enough
研究表明：裂面狀態對k _的大小沒有影響，而對k _的影響卻很大，相同應力條件下，裂面狀態會影響裂紋的開裂角和開裂方式；有限板的邊界對應力強度因子有一定的影響，其k比無限板中的k略大；裂紋間的距離、夾角等因素對裂紋間的干涉效應均有較大影響，裂紋間的干涉效應對應力強度因子的影響非常顯著，只有當裂紋間的距離充分大時，干涉效應才可忽略。 -
