The axisymmetric response of a fluid-filled spherical shell to a local radial impulse--a model for head injury.
This investigation is concerned with determination of the dynamic response of a fluid-filled spherical shell subjected to a local radial impulsive load. From the application point of view, such a fluid-shell system is considered to be a simple, but to date, the most improved theoretical model representing the human head when subjected to impulsive external loads. Analysis is based on linear she...
متن کاملOscillations of magnetic stars II. Axisymmetric toroidal and non-axisymmetric shear Alfvén modes in a spherical shell
We carry out numerical and mathematical investigations of shear Alfvén waves inside of a spherical shell filled with an incompressible conducting fluid, and bathed in a strong dipolar magnetic field. We focus on axisymmetric toroidal and non-axisymmetric modes, in continuation of a previous work by Rincon & Rieutord (2003, A&A, 398, 663). Analytical expressions are obtained for toroidal eigenmo...
متن کاملAxisymmetric Buckling of a Spherical Shell Embedded in an Elastic Medium under Uniaxial Stress at Infinity
The problem of a thin spherical linearly-elastic shell, perfectly bonded to an infinite linearly-elastic medium is considered. A constant axisymmetric stress field is applied at infinity in the matrix, and the displacement and stress fields in the shell and matrix are evaluated by means of harmonic potential functions. In order to examine the stability of this solution, the buckling problem of ...
متن کاملSpherical-shell model for the van der Waals coefficients between fullerenes and/or nearly spherical nanoclusters.
Fullerene molecules such as C(60) are large nearly spherical shells of carbon atoms. Pairs of such molecules have a strong long-range van der Waals attraction that can produce scattering or binding into molecular crystals. A simplified classical-electrodynamics model for a fullerene is a spherical metal shell, with uniform electron density confined between outer and inner radii (just as a simpl...
متن کاملAxisymmetric wave propagation on a conical shell
Equations are derived to describe the propagation of axially symmetric waves generated at the apex of a conical shell, taking into account he coupling between longitudinal and transverse waves. A form of approximate solution is proposed, based upon the Green's function for wave propagation on a fiat plate but containing several variational parameters, the number of which can be reduced to one i...
