摘要: The governing equations of flexural vibrations in a transversely isotropic thermoelastic beam are derived closed form based on Euler–Bernoulli theory. out-of- plane have been studied under different dimensions and boundary conditions. analytical expressions for damping frequency shift obtained. significantly depend thermal relaxation time surface conditions at resonance. displacement temperature fields the resonator Some numerical results with help MATLAB software computed presented graphically silicon material beams.
