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.
