| Abstract |
The finite element method (FEM) has become the most powerful numerical method that is utilized currently for solving problems in mechanics of shells. At the same time, the problem of the construction of curved finite elements for thin shells subject to large displacements and arbitrarily large rotations is still far from being solved [1-3]. This is for that reason that the representation provided by the strain-displacement relationships for rigid displacements of the shell element is inadequate. Therefore, no wonder that since the strain relationships that would be able to represent an arbitrary strain state in local curvilinear coordinates are not available in the literature, the degenerate (isoparametric) element concept [4] has been mostly developed. This concept enables one to represent rigid displacements of the element in the global Cartesian reference frame but requires considerable increase in the computational time [3, 5].
In the literature, there are a lot of versions of both the classical (Kirchhoff-Love) theory of shells and the theory refined on the basis of Timoshenko's hypothesis. However, only some of these theories (e.g., those of [6-9]) provide adequate approximations for rigid displacements of the shell. This observation is validated in [7, 10, 11] for the geometrically linear Kirchhoff-Love theory of shells and in [12] for the refined theory of shells. In the present paper, the results of [12] are extended to shells subject to large displacements and arbitrarily large rotations. |
