Equivalent-Single-Layer discontinuous Galerkin methods for static analysis of multilayered shells

An original formulation for the elastic analysis of multilayered shells is presented in this work. The key features are: representation shell mean surface via a generic system curvilinear coordinates; unified treatment general theories an Equivalent-Single-Layer approach based on through-the-thickness expansion covariant components displacement field; and Interior Penalty discontinuous Galerkin scheme solution set governing equations. combined use these enables high-order problem. Several numerical tests are isotropic, orthotropic with different geometrical configurations boundary conditions, including case non-smooth geometry. Comparisons analytical solutions finite-element simulations show accuracy as well capability robustness proposed formulation, which can be valuable tool generally-curved shells.
