    Notes: Summary A non-linear theory for shallow shells of revolution is presented in this paper. While arriving at the differential equations, large deformations and small strains are taken into account. The solution of equations in the edge zones is based on the boundary layer theory. These boundary layer solutions, predominant in the narrow edge zones are superposed on the interior solutions, to obtain a complete solution of the problem. For the interior solution, linear and non-linear theories are worked out and it is found that the agreement between the two theories is good even when the ratio of the transverse displacement to the thickness of the shell is large.

    Free vibration of deep spherical sandwich shells (1974)
    Springer
    Journal of engineering mathematics 8 (1974), S. 71-79 
    Details

    Notes: Summary This paper deals with axisymmetric vibrations of deep sandwich spherical shells. The shell consists of a thick core and two face sheets of the same isotropic material with equal thickness. The appropriate differential equations have been obtained in terms of two new arbitrary functions which replace the meridional displacement components. The solution is in terms of Legendre functions from which numerical results are computed by using an iterative technique. Effects of geometric and elastic properties of the core and the face sheets are presented in the form of graphs.

    On non-symmetric vibration of deep spherical sandwich shells (1975)
    Springer
    Journal of engineering mathematics 9 (1975), S. 333-341 
    Details
    ISSN: 1573-2703

    Topics: Mathematics , Technology
    Notes: Summary This paper deals with the free non-symmetric vibration of deep spherical sandwich shells. The sandwich shell considered herein consists of three layers. A variational technique is utilized to obtain the equations of motion as well as the appropriate boundary conditions. The effects of transverse shear deformation and rotary inertia have been included in this analysis. New deformation functions have been introduced which considerably simplify the system of differential equations. The final solution is obtained in terms of Legendre functions. Numerical computations have been performed for the symmetric case and graphs are included to show the frequency variation withφ andh/R for various modes.
