Buckling analyses of carbon nanotube reinforced functionally graded composite cylindrical panels

Abstract

This paper investigates the buckling analyses of carbon nanotube (CNT) reinforced composite cylindrical panels via a geometrically nonlinear finite element model with large rotations based on the first-order shear deformation (FOSD) hypothesis. Fully geometrically nonlinear strain-displacement relations and large rotation of shells are considered in the model. First, the proposed model is validated by a frequency analysis of a simply supported CNT reinforced composite cylindrical panel from an existing reference. Then, the model is applied to simulate the behaviors of carbon nanotube reinforced functionally graded (CNT-FG) composite cylindrical panels. The effects of curvature ratio, different buckling behaviors and four representative forms of CNT distributions are studied for their material performance comparatively.

Active vibration control of piezoelectric multilayers FG‐CNTRC and FG‐GPLRC plates

“…In recent years, there has been a surge in publications featuring titles that mention both CNTs and GPLs. These publications primarily focus on analyzing vibrations, [1][2][3][4][5][6] impact response, [7][8][9] effects of cracking, [10][11][12] buckling, and post-buckling behavior [13][14][15] in thermal environments across various structures such as beams, plates, conical shells, and cylindrical shells. One area of research within this field focuses on wave propagation.…”
