Comparison of the theories of geometrically nonlinear shells

A comparison between two approaches to a problem of geometrically nonlinear shells theories has been performed.

The shell strain tensors and equilibrium equations obtained by Duszek [1-3] and Schmidt and Weichert [4] were investigated and compared, t was shown that three of the theories derived by Duszek [1-3] are particular cases of the theory proposed by Schmidt and Weichert [4].
