Abstract

Modulus of elasticity is an important mechanical parameter that characterizes elastic property of materials. In the process of engineering mechanic learning, modulus of elasticity of materials is mainly measured by electrical measurement method. But electrical measurement method requires students being trained for experimental operation that takes long experimental time and uses one strain gauge for one test making high costs of instruments. Consequently, ultrasound measurement method is put forward to measure modulus of elasticity of materials. In this paper, ultrasound measurement method and electrical measurement method are used to measure modulus of elasticity of Mullite ceramic. Experimental results show that modulus of elasticity measured in ultrasound measurement method tests is 27.7Gpa and the measured value in electrical measurement method tests is 28.16Gpa. Comparing the two groups of experimental data,it is found that data obtained by ultrasound measurement method is compact while data obtained by electrical measurement method is dispersed and the average value of two groups variate within 5%. As a consequence,ultrasound measurement method can be used to measure modulus of elasticity of ceramic materials. This method broadens students’ knowledge horizon and improves students’ experiment analytical abilities ,being suited for promotion in college engineering mechanical curriculum with fewer classes and more students participate in experiments.
