Dynamic Buckling of Complete Rigid-Plastic Spherical Shells
Journal of Applied Mechanics, 1974A theoretical investigation is undertaken into the dynamic instability of complete spherical shells which are loaded impulsively and made from a rigid-plastic material. The threshold velocities for the rigid-plastic spherical shells are larger than those for cylindrical shells having the same R/h ratios and material parameters, while the critical mode ...

Creep Buckling of a Complete Spherical Shell
Journal of Applied Mechanics, 1976The creep buckling behavior of a complete spherical shell which is subjected to a uniform external pressure is investigated using a perturbation method of analysis. The spherical shell has an arbitrary initial imperfect shape and is made from a material which creeps according to the generalized Norton’s law.

On the imperfection sensitivity of complete spherical shells
Computational Mechanics, 1987The imperfection sensitivity of elastic complete spherical shells under external pressure is studied for axisymmetric deformations and qualitatively different types of imperfections by means of a numerical analysis of the Reissner shell equations. It is shown that strong reductions of the critical load are obtained for small deviations of the middle ...

Complete dissolution of spherical particles in free-fall
Chemical Engineering Science, 1979A theoretical analysis is undertaken to predict the time-to-complete-dissolution (TCD) of a spherical particle in a diffusion-controlled environment. The well-known and widely-accepted mass transfer coefficient expressions of Frossling and Levich are combined with falling sphere hydrodynamics to yield simple expressions for TCD in terms of the initial ...

Buckling of Complete Spherical Shells and Spherical Caps
1982The buckling behaviour of complete spherical shells and spherical caps is explained and test results are extensively reviewed. The development of the theory up to the point where theoretical and experimental results agree is presented. The treatment is confined to completely elastic material.

Frequency Analysis of Complete Spherical Shells
Journal of the Engineering Mechanics Division, 1969The results of the transverse frequency analysis of complete spherical shells by elastic theory and classical, improved, and membrane shell theories are compared. Fundamental frequencies less than the lowest pure shear frequency of a solid sphere are shown to be accurately predicted by classical shell theory.

Spatio-Temporal Video Completion in Spherical Image Sequences
IEEE Robotics and Automation Letters, 2017Spherical cameras are widely used due to their full 360$^\circ$ fields of view. However, a common but severe problem is that anything carrying the camera is always included in the view, occluding visual information. In this letter, we propose a novel method to remove such occlusions in videos taken from a freely moving spherical camera.

Axisymmetric Free Vibration of Orthotropic Complete Spherical Shells
Journal of Composite Materials, 1988This paper presents studies of the axisymmetric free vibration of moderately thick orthotropic complete spherical shells. The mathematical model is formulated in terms of the mid-surface meridian and radial displacements, and cross-section rotation of the meridians by the improved linear elastic shell theory with the effects of transverse shear strain
