【 摘 要 】

Advancements in aeromechanical materials is a significant topic of research in recent days. Better understanding of structural behaviour is vital for the manufacturing of aircraft and spacecraft components. Sandwich plates can be employed for several applications, especially for making airplane and rocket structures. These all motivate researchers to investigate on the modelling and analysis of advanced materials like carbon nanotubes, laminated composites, functionally graded materials, sandwich structures, etc. Sandwich plates have thin outer facings containing a core in between. The objective of the present work is to conduct a detailed study of the buckling response of sandwich plates employing first order and higher order shear deformation theories considering various aspects. Numerical formulation has been carried out initially. Programing in Matlab environment has been done. Detailed parametric studies also conducted to provide clear understanding of the behaviour of buckling of sandwich structures.
