Abstract: • A novel thermoelastic damping model is established based on Guyer and Krumhansl (G-K) heat conduction model • Inverse quality factor of circular micro-/nano-beam is derived using higher-order shear beam theory • Energy dissipation mechanisms of the shear deformation are combined and analyzed Thermoelastic damping (TED) constitutes a fundamental energy dissipation mechanism inherent in resonators operating at ambient temperatures, with accurate prediction serving as a critical determinant for optimizing high-performance micro-resonator design and fabrication. This paper develops an analytical model of TED for a circular micro/nanobeam based on higher-order shear beam theory (HSBT) where the rotary inertia and shear deformation are taken into account. The Guyer and Krumhansl (G-K) heat conduction model is employed to incorporate both the time relaxation behaviours and the spatially nonlocal effect of heat flow. This study systematically evaluates the impacts of shear deformation, parameters of heat conduction, thermal and vibration modes, boundary conditions, and ambient temperature on TED. The comparation on the classical Euler-Bernoulli beam theory (EBT), Timoshenko beam theory (TBT) and higher-order shear deformation beam theory indicates that shear deformation must be considered. These results provide essential guidelines for designing high-performance micro-resonators with controlled thermoelastic dissipation. [ABSTRACT FROM AUTHOR]
