A Wavelet-Logarithmic Decrement to Identify Damping in MDOF Systems: Theory and Applications
Claude‐Henri Lamarque, S. Pernot · 2001
Abstract A wavelet-based formula similar to the logarithmic decrement formula is introduced to estimate damping in multi-degree-of-freedom systems from time-domain responses. The new formula is then validated upon both numerical and in-situ experiments.
