ON CONSISTENT FIRST APPROXIMATIONS IN THE GENERAL LINEAR THEORY OF THIN ELASTIC SHELLS

The paper is concerned with the rational establishment of two-dimensional differential equations for the approximate analysis of stress and strain in elastic layers with space-curved middle surface. The paper establishes a significant rearrangement of the system of integro-differential equations, in such a way that the nature of the necessary asymptotic expansions is made evident. With this, explicit results are obtained which include the system of two-dimensional constitutive equations of Koiter and Sanders for an isotropic homogeneous medium, as well as a system of constitutive equations for a class of shells for which the normals to the middle surface are not directions of elastic symmetry, as well as a system of constitutive equations for shells which are sufficiently soft in transverse shear to make transverse shear deformation a first-order effect.
