NANO-RESONATOR WITH VARIABLE MATERIAL PROPERTIES
摘要
There are two significant effects in the nanoscale resonator; one is the non-Fourier effect on heat conduction, and the other is the coupling effect of temperature and strain rate. In the present study, a problem of vibration of nano- resonator induced by thermal loading is developed. The governing equations will take into account the above two effects when temperature depends on the mechanical and/or the thermal properties. The modulus of elasticity and the thermal conductivity are taken as linear function of the reference temperature. State-space and Laplace transform methods are used to determine the lateral vibration, the temperature, the displacement, the stress and the stress-strain energy of the nano- resonator. The effects of the relaxation time, thermal loading and the reference temperature in all the studied fields will be studied and represented graphically with some comparisons.
