- 論文の詳細を見る
A copper foil tested is made by tearing off electrodeposited copper on the surface of a stainless steel plate. The foil is about 12μm in thickness. Foil gauges are made by splitting the foil into many pieces in a rectangular for 9 of 2mm×30mm and they are attached to tapered rods of carbon steel which are used as the calibration test specimens subjected to cyclic torsion. When the foil is prestrained, preheated, and left at room temperature for a long time, the effects on the calibration values of the foil gauges are inspected in detail. On the basis of the above results, the methods of improving the sensitivity of the foil gauges are discussed.
