| Abstract |
Thermoelastic damping (TED) is an important factor in modeling and designing of micro-/nanoscale devices. The present study proposes to study thermoelastic damping in piezothermoelastic
beam at nanoscale using nonlocal modified couple stress theory (NMCST) which is a combination of
Eringen’s nonlocal elasticity theory and modified couple stress theory. Coupled thermoelastic equations are derived using NMCST based on Euler-Bernoulli beam theory. The complex frequency
approach has been used to solve the coupled equations and thermoelastic damping has been obtained
for piezothermoelastic nanobeam under simply suppoted-simply supported (SS) boundary condition.
The results obtained are compared to those obtained from classical continuum and heat conduction theories. MATLAB software has been used to discuss the results graphically. |
