Abstract Although “higher-order” and layer-wise “higher-order” plate and shell
theories for composite laminates are widely popularized in the current literature,
they involve (1) postulating very complex assumptions of plate/shell kinematics in
the thickness direction, (2) defining generalized variables of displacements, strains,
and stresses, and (3) developing very complex governing equilibrium, compatibility,
and constitutive equations in terms of newly-defined generalized kinemaic and
generalized kinetic variables. Their industrial applications are thus hindered by
their inherent complexity, and the fact that it is difficult for end-users (front-line
structural engineers) to completely understand all the newly-defined FEM DOFs
in higher-order and layer-wise theories. In an… More >
