基于厚壁圆筒的弹性失效准则所确定的圆筒的初始屈服压力与材料的屈服极限的关系，设计了一种测定厚壁圆筒初始屈服压力的实验方法，并测得了一组实验数据。通过对该实验数据的分析得到了圆筒的初始屈服压力。该实验值与理论值误差较小，表明了该实验方法具有较好的可靠性。

Based on the relation between the incipient yield pressure and the limit of yielding in cylinder according to the elastic disabled rule, a laboratorial method of determining the incipient yield pressure is designed and a set of experimental data were gained. The incipient yield pressure of the cylinder is gained by analyzing the experimental data. The laboratorial method has a good reliability as the experimental value has a little error to the theory value.
