摘要
基于现有自增强理论的材料模型与实际自增强筒体材料的应力～应变关系曲线有显著差异的事实,建立了具有广泛适用性优选模型理论,将优选模型方法与主要的自增强计算过程纳于一套计算软件中,使复杂的计算过程程序化,方便了理论研究与工程应用,并提高了理论计算的准确性。
Based on the fact of obvious difference of the stress～strain figure between thepractical material of autofrettaged cylinders and the present theoretical model, estab-lished was an autofrettage technology program with wide applicability. And the opti-mum seeking model method was developed. The main calculation procedures werebrought within the programs and the autofrettage software system was formed.
