Abstract
In this study, the influence of non-uniform temperature field and temperature-dependent properties on buckling and free vibration behavior of functionally graded carbon nanotube (FG-CNT) reinforced composite cylindrical panel is investigated. For the structural analysis, the finite element method and modal assurance criterion (MAC) analysis are performed. It is found that the temperature-dependent properties and nature of temperature variation fields affect the thermal buckling strength of the panel greatly. The results from MAC analysis reveals that the influence of temperature and nature of temperature variation on buckling and free vibration modes are significant. Further, it is also found that variations in frequencies and associated modes are significant at a temperature closer to buckling temperature. © 2020, Peter the Great St. Petersburg Polytechnic University
