An accurate estimation and modeling of material damping is required for the proper understanding of the dynamic behavior of composite material used in the high-speed rotor-bearing system. Due to the contrasting relevance of material damping as rotating internal damping and stationary external support damping in a high-speed rotor-bearing system, updating methodology is required to be varied. Hence to start with, the finite element numerical model updating of stationary damping of composite material is presented here using the test data extracted from the experimental free vibration and dynamic mechanical analysis (DMA) tests. © 2020 Author(s).Conference Paper
