VIBRATION ANALYSIS OF TEMPERATURE-DEPENDENT FG-CNT REINFORCED COMPOSITE PLATES

The application of functionally graded materials (FGMs) has drastically increased in distinct fields of engineering. In the recent past Carbon nanotube (CNT) reinforced composite has gained significant importance in the material engineering community as a replacement to the conventional FRP composites. This paper deals with the vibration analysis of temperature dependent functionally graded carbon nanotube reinforced composites (FG-CNTRCs). Various types of distributions of single walled carbon nanotubes (SWCNTs) are considered and the material properties of functionally graded carbon nanotube-reinforced composites (FG-CNTRCs) are assumed to be graded through the thickness direction of carbon nanotubes. In the present work free vibration analysis is performed to study the effect of temperature and CNT distribution on natural frequencies of the CNTRC plate. Comparative results for various types of CNTRC plates have also been presented. The results show that CNT distribution and temperature have substantial effect on the vibration characteristics of the FG-CNTRC plate
