摘要: This paper presents a new inverse tangent shear deformation theory (ITSDT) for the static, free vibration and buckling analysis of laminated composite sandwich plates. In present theory, stresses are vanished at top bottom surfaces plates correction factors no longer required. A weak form models based on ITSDT is then derived numerically solved using an isogeometric (IGA). The proposed formulation requires C1-continuity generalized displacements hence basis functions used in IGA fulfill this requirement. Numerical examples provided to show high efficiency method compared with other published solutions.
