First of all, by using of the split-hopkinson pressure bar, the test of siltstone failure/fragmentation under dynamic loading is carried out to investigate the deformation and failure behavior of siltstone after high temperature and the effect of temperature on rock dynamic constitutive relation, peak stress and absorbing energy.

论文作者采用霍普金逊压杆实验系统对高温处理后的粉砂岩进行了单轴冲击加载实验，研究了不同温度处理后粉砂岩的动态力学特性和破坏特征，得出温度对岩石动态本构关系、峰值应力、峰值应变和弹性模量的影响规律。

It is clarified for the first time that the thermal fatigue failure of solder joint is actually a creep strain low cycle fatigue failure, and a physical model for creep fatigue crack propagation has been proposed. It was pointed out that creep strain increases in the high stress area ahead of the tip of thermal fatigue crack, results on one hand that the slide of crack tip increase, inactivation more serious and crack close length increases, the other hand, that intergranular crack exists, whose direction will affect the fatigue crack propagating.

本文首次阐明了焊点的热循环失效本质上是以焊点内循环蠕变为主要应变的低周疲劳失效，并在此基础上提出了蠕变疲劳裂纹扩展的物理模型，指出热循环裂纹前端的高应力区内，蠕变加剧，使裂纹前端滑移增加，裂纹钝化加剧，导致随后的裂纹闭合扩展长度增加；同时蠕变也使裂纹前端的高应力区出现晶间裂纹，蠕变沿晶裂纹对主裂纹扩展的影响取决于沿晶裂纹的连接方向。

It was found that: the failure form of the stubble will be splitting and breaking when the stalk is cut by single blade; And it will be axial direction crack by torsional shearing stress, splitting and breaking by bending stress when the stalk is cut by two or more blades one by one.
