This paper investigates the stability and shape evolution of voids and channels under the combined effects of surface misfit, surface energy and surface diffusion. A dynamic model that incorporates the competition among these energetic forces is developed. Our approach integrates a novel local semi-implicit level set method to capture interface movement and an iterative spectral method to calcu...

In previous work, a series of theoretical considerations have been made aimed at identifying the source and assessing prominent factors influencing the thermoelastic response from laminated composites. In this paper four different methods of interpreting the data are investigated and the theoretical thermoelastic response is compared to experimental data to identify the source of the thermoelas...

this paper presents a nonlinear model of a clamped-clamped microbeam actuated by an electrostatic load with stretching and thermoelastic effects. the frequency of free vibration is calculated by discretization based on the differential quadrature (dq) method. by separating the real and imaginary parts of frequency, the quality factor of thermoelastic damping is calculated. both the stretching a...
