Famous Log Decrement Method 2022. Method the logarithmic decrement is defined as the natural log of the ratio of the amplitudes of any two successive peaks: The logarithmic decrement is the natural log of the ratio of the amplitudes of any two successive peaks:
Provides an introduction to using log decrement to find damping ratio of an underdamped system from measured response data It represents an archaic (or quick) method to calculate the approximate damping ratio and damped natural frequency from. The logarithmic decrement is the natural log of the ratio of the amplitudes of any two successive peaks:
