On refined constitutive equations in the six-field theory of elastic shells

Abstract

Within the resultant six-field shell theory, the second approximation to the complementary energy density of an isotropic elastic shell undergoing small strains is constructed. In this case, the resultant drilling couples are expressed explicitly by the stress resultants and stress couples as well as by amplitudes of the quadratic and cubic distributions of an intrinsic deviation vector. The refined 2D strain-stress and stress-strain constitutive relations for shells are found, in which the effect of curvatures of the shell midsurface is consistently taken into account.
