Abstract: The Bjerknes method of determining the logarithmic decrement of the secondary of two coupled circuits is critically discussed. The Author suggests a new method for determining this decrement ...

The damping of spruce wood is analysed at different moisture content levels for the first three vibration modes of tangentially and radially vibrating samples. Two methods were used to determine the ...

This folder contains scripts for testing linear damping identification methods on time histories representative of a linear SDOF system without noise. The examined methods are the logarithmic ...
