基于统一屈服准则（UYC），在有限应变框架下对薄壁圆管进行了塑性失稳分析。推导出了适用于各种非强度差材料的无缺陷圆管端盖爆破压力的统一解析解。从这个统一的解可以推导出一系列的解，这些解是基于Tresca，von Mises的爆破压力解。ASSY准则和TS准则是其特例，通过与已有试验结果的比较，发现本文提出的统一解对爆破压力的预测是非常方便和有效的。(C)2011爱思唯尔有限公司保留所有权利。
Based on a unified yield criterion (UYC), the plastic collapse analysis of thin-walled pipes is conducted in the framework of finite strain. A unified analytical solution for the burst pressure of end-capped defect-free pipes is derived, which is fit for various kinds of non-SD (strength differential) materials. A series of solutions can be deduced from this unified solution, and those solutions of burst pressure on the basis of Tresca, von Mises. ASSY, and TS criteria are special cases of it. By comparing with existing test result, it is found that the present unified solution is very convenient and effective for the prediction of burst pressure. (C) 2011 Elsevier Ltd. All rights reserved.
