摘要
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,设计了一种测定材料屈服极限的实验方法,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,最终求得了材料的屈服极限.由于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.该方法对研究材料的机械性能及压力容器的失效规律具有一定的工程实际意义和理论价值.
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 limit of yielding of material is designed and a set of experimental data were gained by the method. The incipient yield pressure of the cylinder is gained by analyzing the experimental data, and then the limit of yielding is gained. The laboratorial method has a good reliability as the experimental value has a little error to the theory value. It has a definite engineering signification and theory value to research the mechanical capability of material and the disabled rule of high pressure vessel.
