Abstract
Adopting an effective layup sequence in laminated composite structures has always compelled scientists to investigate the behavior of laminated composite constructions. The present article presents the buckling analysis of double- and cross-helicoidal laminated composite plates using recently proposed HOZT. The Buckling behavior of helicoidal plates is compared to that of quasi-isotropic and cross-ply laminated composite plates. Higher buckling loads are seen for helicoidal plates, particularly those with free edges. The influence of skew angle, aspect ratio, thickness ratio, and plate end conditions on the helicoidal plate’s buckling behavior are also investigated.
