A generalized linear model of dynamics of thin elastic shells by E.Yu. Mihajlova, D.V. Tarlakovskii, G.V. Fedotenkov

“…It has been shown that the movements of any point of the shell are determined by the tangential and normal displacements of the middle surface, by two angles of rotation of the normal fiber and its deformation, and the deformed state of the envelope is specified by the tensors of tangential deformation and changes in curvature and deformation of the normal fiber. By means of the linearization of the equations of compatibility of deformations for a continuous medium, three analogous equations for a thin shell have been obtained. …”
