集中载荷作用下开顶扁球壳的非线性稳定问题的渐近解
Asymptotic Solutions of the Nonlinear Stability of a Truncated Shallow Spherical Shell under a Concentrated Load
-
Abstract: In this paper, the nonlinear stability problem of a clamped truncated shallow spherical shell with a nondeformable rigid body at the center under a concentrated load is studied by means of the singular perturbation method. When the geometrical parameter k is large, the uniformly valid asymptotic solutions are obtained.
