A hybrid discontinuous Galerkin semi-discrete finite element method for skewed and curved laminated beams/plates/shells based on Delta function

The laminated plate and beam with clamped boundary conditions are studied. The interface shear stress is compared with ANSYS. Numerical oscillation is not observed for the second type Delta function with equal-order interpolations of displacement and interface stress. Skewed and curved laminated plates are also analyzed. The accuracy is still good for various angles between adjacent edges and various curvatures.
