Ellipsoidal ShellNonuniform StrainWithin a variational approach, a system of nonlinear equations is obtained to analyze elastoelectric effects in a disordered homogeneous nonconducting medium. The results of analysis are applied to the case of a spherical shell subject to centrosymmetric hydrostatic ...

It is shown how two of their fundamental linear limit forms corresponding to two known classes of problems: 1) determining the influence of a permanent magnetic field on the free vibrations of elastic shells /1/, and 2) the determination of the shell deformation due to ponderomotive forces ...
Mathematical modelsWe study the flow of electrical currents in spherical cells with a non-conducting core, so that current flow is restricted to a thin shell below the cell's membrane. Examples of such cells are fat storing cells (adipocytes). We derive the relation between current and voltage...
