摘要
在实验的基础上,本文利用F.Barlat-Lian(B-L)屈服函数来描述钛板屈服应力与r值之间的定量关系。统计处理表明:M=8～12时,关系式与实验数据吻合很好,并据此推荐出一个压力容器强度计算式。
Based on the experimental data, a quantitative relationship between yield stress and r-value of Ti sheet was expressed by the F. Barlat-Lian yield function. In statistic estimation, the suitable results after the formula were in agreement with the experimental data thus, an equation was suggested to estimate strength for pressure vessel made of Ti sheet.
