A New Type of Measuring Instrument for Shear Modulus of Elasticity

Abstract

In order to determine the shearing properties of material accurately, a new instrument for shear force was developed. In the Measuring Instrument, the linear motor was used as driving mechanism, the force sensor was used to collect the shear force of material, meanwhile displacement was measured by the transducer, and then the stress was calculated by computer. And the relationship of stress and strain relation was got. The design of clamping mechanism was optimized, which avoided the slip phenomenon. So the measurement error is reduced greatly.
