Computational analysis of material-dependent damping in riveted fixed beams using ANSYS workbench R19.2

Journal of Materials Science: Materials in Engineering
Damping is a crucial factor in structural dynamics as it dissipates energy and reduces vibrations. Proper damping is essential to prevent failures caused by resonance in vibrating structures. Layered through thickness and then fastened beams possess more

Evaluation Damping Performance for Hydrostatic Bearing Film by Damping Ratio Scaling

DEStech Transactions on Computer Science and Engineering, 2019
This paper investigates how to evaluate the damping ratio in practical measurement for hydrostatic bearing which possesses overdamped damping. The traditional methods such as decayed response, band width of resonant peak, transient response of step excitation and hysteresis circle cannot be utilized for get over overdamped behavior.
