Abstract
Astudy oftheeffectofanisotropyoffacesheetsonbuckling andpostbuckling ofsandwiche atpanelssubjected to both mechanical and thermal loads is presented. Themechanical loadsconsist of uniaxial compressive/tensile edge loads, while the temperature is assumed to exhibit an antisymmetric variation through the panel thickness. The study iscarried outin thecontextofa geometrically nonlinear theory of sandwichstructuresthat also incorporates the effect of unavoidable stress-free initial geometric imperfections. A detailed analysis of the ine uence of a large number of parameters associated with the panel geometry, material properties of the core, e ber orientation and stacking sequence in the face sheet, and character of tangential boundary conditions (i.e., movable or immovable ) on buckling strength and postbuckling response is accomplished, and pertinent conclusions are outlined.
