Stress–Strain State of a Two-Layer Circular Orthotropic Plate with Low Shear Stiffness

The plane and bending problems for a circular elastic plate with two dissimilar cylindrically orthotropic layers are solved. The bending problem is solved using refined theories. It is hypothesized that the distributions of radial displacements in the layers are described by different linear functions of the transverse coordinate. The interaction of the layers is described as the action of the normal and tangential contact stresses represented by power polynomials with unknown coefficients determined from conditions of perfect bonding between the layers. A specific example is considered. Quantitative and qualitative conclusions are drawn. © 2014, Springer Science+Business Media New York.
