Full Article:

In this paper, we expound a general theory valid for shallow shells, either thin or moderately thick, inspired as a generalization for plates according to the Bolle-Reissner theory, with necessary modifications to include the thinnest shells. The immediate antecedent is constituted by the elastic study of plates shown in the work "General Equations Transformed and Expanded for a General Study of Isotropic Plates Starting with the Bolle-Reissner Theory as a starting point" (submitted also to this Congress). In short, although we esteem this to be an original proposal, it is inspired in a methodology partly known in plates which provides us with a system of differential equations easily tackled by finite differences. Also, as it is valid for moderately thick shells, it does not pose any problems of numerical instability when carrying out studies of thin shells and although it has been constrained to shallow shells, it can be applied to the resolution of a great variety of practical cases given the limitations which have to be imposed in order to consider them as shallow shells (which is usually common in constructive cases).
