190) 12 which are the classical membrane and bending stiffnesses for an orthotropic shell. With the above definitions, the expression for the internal virtual work for a composite shell may now be compactly written as Kbend = δWint = − Γ0s δεε · Kexteε + Kcoupκ dΓ − Γ0s δκκ · Kcoupε + Kbendκ dΓ. 192) where Γts h is the shell subdomain with a prescribed traction boundary condition, and ρ0 is the through-thickness-averaged shell density given by ρ0 = 1 hth ρ0 dξ3 . 192), we omitted the terms corresponding to the prescribed traction on the edges of the shell.

An alternative linearization of the follower pressure load, which uses the parametric coordinates of the boundary surface, may be found in Wriggers (2008). 1 Thin Structures: Shell, Membrane, and Cable Models Kirchhoff–Love Shell Model In this section we follow the developments of Kiendl et al. (2009, 2010) and Bazilevs et al. (2011c) that present the governing equations of the Kirchhoff–Love shell theory. The theory is appropriate for thin-shell structures and, when discretized using smooth basis functions, requires no rotational degrees of freedom.
