From: Damping of selectively bonded 3D woven lattice materials
(a) The Laser Doppler Vibrometry (LDV) equipment measured the frequency response of 3D woven lattice at high frequencies. (b) Damping loss factor \(\eta \) as a function of the forcing frequency measured with the dynamic mechanical analyzer (DMA) and Laser Doppler Vibrometer, and obtained from FE simulation. Notice that the damping loss factor increased with the forcing frequency.
