摘要
以Miner、Boltsman叠加原理为代表的线性叠加原理在探讨低应力水平的蠕变叠加作用时存在很大困难,文章对此进行了分析讨论,并在此基础上建议了一种非线性叠加原理,在实际应用中得到了很好的验证.
For creep caused by lo w stress, Minerand Boltsman superposition methods cease to be ef fective. In this paper the superposition methods are discusscd, and a nonlinear superposition method is proposed and verified by calculations based on tests.
