Buckling of Spherical Shells Revisited
A study is presented of the post-buckling behavior and imperfection-sensitivity of complete spherical shells subject to uniform external pressure. The study builds on and extends the major contribution to spherical shell buckling by W.T. Koiter in the 1960’s. Numerical results are presented for the axisymmetric large deflection behavior of perfect spheres followed by an extensive analysis of th...
متن کاملBuckling Analysis of Concrete Spherical Shells
In some simple two-dimensional structures it is sufficient to determine only the lowest value of the load at which buckling commences. However, in the case of shells, it may be also necessary to investigate the postbuckling behavior because it has an important bearing on the magnitude of the failure load. The importance of the postbuckling behavior, which the small deflection theory of buckling...
متن کاملThe Geometric Role of Precisely Engineered Imperfections on the Critical Buckling Load of Spherical Elastic Shells
We study the effect of a dimple-like geometric imperfection on the critical buckling load of spherical elastic shells under pressure loading. This investigation combines precision experiments, finite element modeling and numerical solutions of a reduced shell theory, all of which are found to be in excellent quantitative agreement. In the experiments, the geometry and magnitude of the defect ca...
متن کاملParametric Resonance in Spherical Immersed Elastic Shells
We perform a stability analysis for a fluid-structure interaction (FSI) problem in which a spherical elastic shell or membrane is immersed in a 3D viscous, incompressible fluid. The shell is an idealized structure having zero thickness, and has the same fluid lying both inside and outside. The problem is formulated mathematically using the immersed boundary framework in which Dirac delta functi...
