A NEW APPROACH TO THE MECHANICS OF ORTHOTROPIC MULTILAYERED PLATES

New methods are developed which provide a simplified treatment of the mechanics of multilayered and strongly orthotropic plates. It includes the case where individual layers are themselves constituted by thinly laminated materials each with their own orthotropic and microelastic properties. The fundamental skin effect of anistropic solid mechanics is taken into account. The theory is derived in the context of plane strain deformations. Recurrence equations are obtained for an arbitrary number of layers and applied to plates with two and three layers.The microelastic stress-couple is evaluated for the case of laminated media. Characteristic physical features are discussed and the results are compared to a treatment based on the classical Euler-Bernouilli and Timoshenko models. (Author)
