本文是在笔者推导的自增强厚壁园筒初始残余应力分布计算式[1]的基础上,进一步提出了在交变内压作用下自增强厚壁园筒残余应力的松弛模型,并以试验数据对其进行了验证。
Based on the calculation formula of the initial residual stress of self-reinforced thick-walled cylinder deduced by the author, a relaxation model of the residual stress of self-reinforced thick-walled cylinder under alternating internal pressure is proposed. Based on the experimental results The data verified it.
