Popis: In the present study, an analytical solution for the static analysis of orthotropic plates under combined thermal and mechanical loading has been developed using the hyperbolic shear deformation theory. The hyperbolic sine and cosine function is used in the displacement field in terms of thick ness coordinate to represent the effect of transverse shear deformation. The most important feature of the theory is that transverse shear stresses can be accurately calculated by the direct constitutive equation approach. The present theory contains the same number of dependent variables as in the first-order shear deformation theory. The governing equilibrium equations and boundary conditions of the theory are obtained using the principle of a virtual work. Simply supported orthotropic plates subjected to a sinusoidal and uniformly distributed thermal and mechanical load is considered for the detail numerical study. Navier solution technique is employed for the simply supported plates. The program has been developed in FORTRAN. Results are obtained for displacements and stresses. The present solutions are compared with those obtained by other researchers. The results are in good agreement with the solution presented by other shear deformation theories.
