非线型固体杨氏模量测量

Measurement of nonlinear solid Young's modulus

本实验利用时差法测得超声波在非线型固体介质中纵波的传播速度,根据待测物体的密度,从而计算出非线型固体物质的杨氏模量。该实验的测量原理简单,方法直观可行,测量结果可靠。

The transit-time measurement was ultrasonic propagation velocity of longitudinal waves in the non linear solid media. This paper calculates the density of the tested object and Young＇ s modulus of nonlinear sol id materials. The measurement principle is simple, intuitive and feasible, and the measurement results are reli able.
