Vibrational Energy Flow Model for a High Damping Beam with Constant Axial Force

Vibrational Energy Flow Model for a High Damping Beam with Constant Axial Force

The energy flow analysis (EFA) method is developed to predict the energy density of a high damping beam with constant axial force in the high-frequency range. The energy density and intensity of the beam are associated with high structural damping loss factor and axial force and introduced to derive...
