| Abstract: | Young's Modulus of different materials at different temperature are investigated in this paper.The effects of the geometric dimensions of the samples,as well as the location of the hanging thread on measuring and the determining of the true and false resonance peaks are analyzed.The result shows that the dynamic method of Young's Modulus has the features of low energy consumption and high sensitivity,and its precision is of one order of magnitude higher with respect to that of the traditional static tensile method. |
