Buckling Analysis of Functionally Graded Shallow Spherical Shells Under External Hydrostatic Pressure
The aim of this paper is to determine the critical buckling load for simply supported thin shallow spherical shells made of functionally graded material (FGM) subjected to uniform external pressure. A metal-ceramic functionally graded (FG) shell with a power law distribution for volume fraction is considered, where its properties vary gradually through the shell thickness direction from pure me...
متن کاملBuckling 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 کاملbuckling interaction for spherical shells subject to pressure and probing forces
Elastic spherical shells loaded under uniform pressure are subject to equal and opposite compressive probing forces at their poles to trigger and explore buckling. When the shells support external pressure, buckling is usually axisymmetric; the maximum probing force and the energy barrier the probe must overcome are determined. Applications of the probing forces under two different loading cond...
