本文应用能量的方法,对变壁厚的圆柱套管在静水外压下的弹性失稳问题;对非均匀壁厚椭圆套管的抗挤强度理论计算问题,分别作了论述。同时,对后者所涉及的几个特定问题也进行了讨论。
In this paper, the energy instability problem of cylindrical casing with variable wall thickness under hydrostatic pressure is studied by using the energy method. The theoretical calculation of the collapse strength of the non-uniform wall thickness elliptical casing is discussed respectively. At the same time, some specific problems involved in the latter are also discussed.
