Examples
- A suit of dynamic indentation experimental system is design and establish firstly in the country which is based on static indentation experimental theory and shpb theory
本文是国内首次根据静态压痕试验理论和shpb理论设计和建立了一套动态压痕试验系统,它由动态压痕试验装置、应变测量电路、数据采集系统组成。 - It includes dynamic indentation experimental equipment , strain measuring circuit , data acquisition system . this system can be used to implement dynamic indentation experiment on the material surface
这套系统可以用来对材料进行动态压痕试验,获得材料的动态力学参数,也可以获得材料的动态应力-应变曲线,从而分析材料的动态塑性性能。 - It is found that the great cracks on the coarse surface are initiated easily than on the smooth surface by the sem observation and the crack size obtained at the dynamic indentation experiment is bigger than at the static indentation experiment under the same load . it is showed the single crystal silicon is easier to initiate the crack and fracture under dynamic load , the single crystal silicon ’ s
然后通过sem观察单晶硅试件表面压痕形貌,发现粗糙表面比光滑表面容易生成大裂纹,在相同载荷作用下单晶硅材料在动态压痕试验得到的裂纹要大于在静态压痕试验得到的裂纹,表明在动态加载条件下单晶硅材料更容易生成裂纹和破碎。 - It can obtain the material ’ s dynamic mechanics parameters and also obtain the plot of the material ’ s dynamic stress - strain to analyze the material ’ s dynamic plastic properties . it is concluded that the single crystal silicon ’ s hardness under the dynamic indentation experiment is less than under static indentation experiment and the hardness obtained on the coarse surface is less than on the smooth surface
其次通过对单晶硅材料粗糙表面和光滑表面分别进行动态压痕试验和静态压痕试验,发现单晶硅材料粗糙表面的硬度值小于光滑表面的硬度值,单晶硅材料在动态加载条件下的硬度值小于静态加载条件下的硬度值。
