Abstract

This paper presents the development of a test procedure and application of non-contacting strain measurement in dynamic tensile testing. The strain time histories of test specimens measured by a laser extensometer were derived by a phase-shift technique based on zero-crossing method. The accuracy of proposed procedure was verified by comparing the strain values measured by the laser extensometer with the actuator measurement of a servo-hydraulic high speed machine using aluminum alloy (AA) 6061-T6, and then applied to Alkaline Resistant (AR) glass fabric reinforced cement composite. Comparison between these two measurements shows a good agreement. The strain rate effect on the mechanical properties of AR-glass fabric-cement composite was found. The failure behavior of the composite was also discussed using the images captured by high speed camera.
