Measuring the Elastic Modulus and Poisson's Ratio of Corncob by Electrical Method

Abstract:

The Elastic Modulus and Poisson's ratio of corncob were Measured by electrical method.The sensor was electric-resistance strain gauge.When the corncob was applied by force,the strain of corncob transformed into resistance changing of the sensor.Then,measure the resistance by SINOCERA YE253 programmable static strain gauge and transmit the resistance into the strain.It was found that the Elastic Modulus of corncob under the moisture content of 10.5% is 1.208×10⁹ Pa and the Poisson's ratio is 0.33.
