In-plane Strain and Stress Fields in Theories of Shearable Laminated Plates Subject to Transverse Loads
The predictions of a new theory of orthotropic laminated plates are compared with those of two other theories equally based on a Reissner-Mindlin Ansatz for the displacement field, either layer by layer [5] or...
