Buckling of laminated sandwich plates with soft core based on an improved higher order zigzag theory

Effect of Initial Stress on the Dynamic Response of a Multi-Layered Plate-Strip Subjected to an Arbitrary Inclined Time-Harmonic Force

“…The monographs [1,2] give detailed information on the subject. Some examples of studies made on the influence of initial stresses on the multilayered system are given in [3][4][5][6][7][8][9][10].…”

Assessment of inverse trigonometric zigzag theory for stability analysis of laminated composite and sandwich plates

“…As the analytical methods are limited to some specific geometry, loading and boundary conditions, Di Sciuva [17] represented static, buckling and vibration analysis of composite laminate using finite element (FE) approach based on zigzag theory (ZZT). Buckling of laminated sandwich plates based on an improved higher order zigzag theory was studied by Pandit et al [18] considering the core compressibility effect. Singh et al [19] studied the buckling analysis of laminated composite and sandwich plates using finite element procedure based on a higher order zigzag theory derived by the same author.…”

Assessment of the Refined Zigzag Theory for bending, vibration, and buckling of sandwich plates: a comparative study of different theories

“…Xiaohui and Wanji [30], by using a third-order zigzag model, developed an improved C 0 -continuous plate finite element and applied it to the natural frequencies problem of sandwich plates with soft cores. Pandit et al [31,32] formulated a higher-order ZZ model where the in-plane displacements are assumed to be cubic across the thickness and the transverse displacement is constant across the face thickness and varies according to a second order polynomial through the core thickness. Based on this kinematic assumption, a C 0 -continuous plate finite element model was developed and applied to the bending, vibration and buckling loads problem of soft core sandwich plates [31,32].…”
