- Abstract
Elastic index is the required important parameters in the theoretical analysis and design calculation of components. Mechanical testing method and electrical measuring method are commonly used in engineering mechanics experimental. This article discusses the ultrasonic method which is used to measure the material elastic index. In this paper, Using ultrasound method to measure the elastic index of 1095 steel, and comparing with literature values ultrasound measurement method and electrical measurement method are used to measure modulus of elasticity of Mullite ceramic. Experimental results show that the ultrasonic measured elasticity coefficient value is very similar with literature value; 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%. This method has benefits such as no use of strain gauge,low costs, short cycle and multi-point measurement, thus it is suitable for multi-person experiment. In addition, this method can broaden students’ knowledge horizon and cultivate independent thinking ability and practical ability.
