本文讨论位于弹性介质中的组合管筒的平衡问题,管筒受均匀内压力并考虑材料的非线性蠕变。我们利用工作〔1〕中线性解的方法来解这个问题。这方法的特点是:不是取弹性解作为第一次近似,而是取相应的线性蠕变问题的解作为第一次近似。正由于这一特点,大大的加快了逐次近似的收敛 In this paper, we discuss the problem of the equilibrium of a combined tube in a flexible medium under uniform internal pressure and considering the nonlinear creep of the material. We use the work [1] in the linear solution to this problem. The characteristic of this method is that instead of taking the elastic solution as the first approximation, the solution of the corresponding linear creep problem is taken as the first approximation. It is because of this feature, greatly accelerating the convergence of successive approximations
