Evaluation of Elastic Properties of CP Ti by Three Different Techniques

Abstract

Elastic constants are the fundamental key parameters in the mechanical behaviour of engineering materials under stressed condition. This paper explains the determination of elastic constants of commercially pure titanium (Grade-2) at ambient temperature using three independent test methods including quasi-static tensile test with strain gauged specimen, ultrasonic pulse echo method and resonance based impulse excitation technique. The results are statistically analysed and compared.
