Effect of Face-Sheet Anisotropy on Buckling and Postbuckling of Sandwich Plates

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