Title: Method for measuring damping factor of material
Inventor: DEGAWA TOORU
IPC: G01N3/32
Filed: 1981-10-31
Abstract: PURPOSE:To make it possible to perform measurement under the conditions measurement has been difficult by conventional methods, by arranging two kinds of materials, i.e. a sample to be measured and a reference sample whose damping factor is small in series, applying forced vibrations to these samples, and leading the strain of each sample to a combination bridge circuit. CONSTITUTION:An arbitrary frequency is selected from an oscillator 1. Thereafter a vibration applying machine 3 is operated. A load in the pressure drawing direction is applied to the material to be measured S and the sample material R whose damping factor is small which are arranged in series. The difference in strain caused between these materials is detected through a bridge circuit 6. The difference between hysteresis loops of two samples is obtained in an X-Y recorder. The hysteresis loop obtained in this way can be converted as the  difference in the damping factor between both samples by an expression of relation with regard to a loop area and a logarithmic damping rate IF. By using the  material having extremely low damping factor in comparison with the material  to be tested in this method, the measurement can be performed under the conditions wherein the conventional measurement cannot be performed.
