Deformation velocity has no obvious effect on the flow of material, initial yield stress and flow stress.
变形速度对材料流动、初始屈服应力、流动应力影响不明显。
The initial yield pressure of the cylinder is gained by analyzing the experimental data, and then the yield limit is calculated.
通过对该试验数据的分析得到了圆筒的初始屈服压力，最终求得了材料的屈服极限。
The result shows that the impact velocity of initial yield is very small for the soil, and the cohesion has an obvious influence on it while the internal friction Angle does relatively small.
研究结果表明：土体初始屈服冲击速度非常小，其中黏聚力对其有较大影响，而内摩擦角对其影响相对较小。
Initial yield pressure of monolayered cylinder with the same size was considered as the SPT pressure, based on the analysis among pressure test, plastic fault theory and self enhancement treatment.
