Abstract
An active constrained beam subjected to temperature was analyzed for its vibration and damping behavior under thermal environment. The loss factor variation and frequency variation in respect to temperature considering the the temperature dependent core shear modulus and temperature dependent material loss factor of the core were reported. The temperature field in the beam was calculated by using 4 noded rectangular elements. Results indicated that as core thickness increases, passive damping in the beam increases.
