基于净截面失稳准则的周向裂纹管塑性极限载荷通用解

The General Equations of Plastic Limit Load Based on the Net Section Collapse Criteria for Circumferentially Cracked Pipes

基于净截面失稳准则建立了拉弯组合受载条件下周向埋藏裂纹厚壁管的塑性失稳极限载荷状态受力模型。

Based on the net section collapse criteria,the analytical model of plastic limit load has been established,from which the general equations of plastic limit load have been derived for thick-wall pipes with circumferentially embedded cracks under combined tensile and bending load.
