Buckling and Thermomechanical Vibration Analysis of a Cylindrical Sandwich Panel with an Elastic Core Using Generalized Differential Quadrature Method
In this paper, the vibrational and buckling analysis of a cylindrical sandwich panel with an elastic core under thermo-mechanical loadings is investigated. The modeled cylindrical sandwich panel as well as its equations of motions and boundary conditions is derived by Hamilton’s principle and the first-order shear deformation theory (FSDT). For the first time in the present study, various bound...
متن کاملVibration and Critical Speed of Axially loaded Rotating Orthotropic Cylindrical Shells
In this paper, classical thin shell theory is used to analyze vibration and critical speed of simply supported rotating orthotropic cylindrical shell. The effects of centrifugal and Coriolis forces due to the rotation are considered in the present formulation.. In addition, axial load is applied on cylinder as a ratio of critical buckling load. Finally the effects of orthotropic ratio, materia...
متن کاملComputation of Localized Post Buckling in Long Axially-Compressed Cylindrical Shells
Buckling is investigated of a long thin cylindrical shell under longitudinal compression as modelled by the von KK armm an{Donnell equations. Evidence is reviewed for the buckling being localised to some portion of the axial length. In accordance with this observed behaviour the equations are rst approximated circumferentially by a Galerkin procedure, whereupon cross-symmetric homoclinic soluti...
متن کاملBuckling of axially compressed thin cylindrical shells with functionally graded middle layer
Buckling of a simply supported three-layer circular cylindrical shell under axial compressive load is studied. The inner and outer layers of the shell are comprised of the same homogeneous and isotropic material, and the middle layer is made of an isotropic functionally graded (FG) material whose Young’s modulus varies either affinely or parabolically in the thickness direction from its value f...
متن کاملOptimization of an Axially Compressed Ring and Stringer Stiffened Cylindrical Shell with a General Buckling Modal Imperfection
PANDA2, a computer program for the minimum-weight design of elastic perfect and imperfect stiffened cylindrical panels and shells under multiple sets of combined loads, is used to obtain optimum designs of uniformly axially compressed elastic internal T-ring and external T-stringer stiffened cylindrical shells with initial imperfections in the form of the general buckling mode. The optimum desi...
