For rock samples under uniaxial compression test, its failure forms include friction slippage, self-similar propagation and crankle expansion of microcracks.

对于单轴压缩的岩石试件，其破坏型式主要是微裂纹的摩擦滑移、自相似平面扩展和弯折扩展。

At the same time, based on crack expansion, a computation method of damage cumulation is suggested.

同时，提出了一种基于裂纹扩展的损伤累积计算方法，并用实例计算说明了其合理可行。

The results show that, when the electromagnetic field was applicated, the flowability and filling capacity of cupronickel alloy are increased, the surface cracks are eliminated, and the thin-walled cupronickel tube billets with smooth surface can be obtained due to the increase of flowability and filling capacity of cupronickel alloy. The solidification structure of the tube billets is evidently refined, the shape of Ni-rich phase changes from needle-like to bulk and the casting stress declines from 7.2 to 0.32 MPa. With the structure improving, the tensile strength and elongation increase by 5% and 36%, respectively, than those of ordinary continuously cast tube billets.

结果表明：在连铸过程中施加旋转电磁场能够提高金属液的流动性和充型能力，消除表面裂纹缺陷，从而制备出表面光滑的薄壁白铜管坯；在电磁力的作用下管坯凝固组织显著细化，富镍相由针状转化为团块状，同时铸造应力由未施加电磁场时的7.2 MPa下降至0.32 MPa；随着凝固组织的改善，施加磁场的管坯抗拉强度和伸长率与未施加磁场管坯的相比分别提高5%和36%。
