An arbitrary sandwich shell is studied by deriving the equations of equilibrium and the boundary conditions by the minimum potential energy theory. The general equations are then reduced to the case of a spherical sandwich shell. The deflection, displacements, and rotations are found in terms of Legendre functions and their derivatives. A particular case of a hemispherical sandwich shell clamped along the base and subjected to a uniform pressure is solved. Typical geometrical and mechanical properties are selected and numerical results obtained. Author
