Thermal Buckling of Thick Laminated Composite Plates under Uniform Temperature Distribution

균일분포 온도하의 두꺼운 복합 재료 적층판의 열적 좌굴 해석

In this paper, the thermal buckling of thick composite angle-ply laminates subject to uniform temperature distribution is studied. For the plates of 4-edges simply supported condition and those of 4-edges clamped condition, the critical buckling temperatue is derived, using tile finite element method based on the shear deformation theory. The effects of lamination angle, layer number, laminate thickness, plate aspect ratio and boundary constraints upon the critical buckling temperature are presented.
