Open access ethresearch Under the premise of homogeneous force, or curvature-gradient, distribution, a solution for transverse-shear strains and stresses, warping functions and through-thickness is derived by satisfying all relations and conditions of linear elasticity. Only for calculating the substitute-plate transverse-stiffness matrix the principle of the minimum of the total potential energy is used as a scheme for correctly combining energetically conjugate components of stresses and strains for the entries of the substitute-plate transverse stiffness matrix. The model is valid for all laminate and sandwich designs. The said premise renders the model a point theory rather than a structural theory, so that it is a complement to the classical theory of laminated plates in the sense of mapping substitute-plate properties and distribution of state variables through the laminate thickness. This paper explains the modeling ideas and derivations in detail. Predictions of the responses for a set of sample laminates of varying complexity, and comparison of stiffness values with those obtained by a dedicated FEM formulation, verify the model. 5th International Conference on Mechanics of Composites, MECHCOMP in Lisboa, Portugal (July 1-4,2019) In Copyright - Non-Commercial Use Permitted http://rightsstatements.org/page/InC-NC/1.0 ethresearch Filipovic Daniel joint author http://hdl.handle.net/20.500.11850/355071 text/html WWW-Backlink auf das Repository (Open access) 1 Other Conference Item ethresearch ETHRESEARCH 856 40 http://hdl.handle.net/20.500.11850/355071 text/html WWW-Backlink auf das Repository (Open access) ETHRESEARCH 100 1- Kress Gerald ETHRESEARCH 700 1- Filipovic Daniel joint author CL050000 XL050000 XC000500 ETHRESEARCH ETHRESEARCH ETHRESEARCH Other Conference Item Open access
