摘要
在分析压应力作用下裂纹扩展模型的基础上,指出了目前几种常用的岩石中平面分支裂纹尖端应力强度因子的近似解析式所存在的问题,并给出了应力强度因子的较为简便且合理的近似表达式.
By analyzing crack extension model under compressive stress,the problems existing in approximate expression of stress intensity factors of tip of planar branch crack in crack, which are always used, are pointed out; and a simply and rationally approximate expression of stress intensity factors is given also.
