Comparison of Elasticity, Shell Core, and Sandwich Shell Theories
the problem of an infinite circular sandwich shell subjected to an axisymmetric radial line load is investigated using three-dimensional elasticity theory, shell core method, and sandwich shell theory due to Fulton and Schmidt. A comparison of the stresses and displacements with an exact elasticity solution is carried out for various shell parameters in order to clearly bring out the limitations of sandwich shell theories of Fulton and Schmidt as well as the shell core solutions.
