将兰姆波入射到纯镁板中进行疲劳试验，检测到板中产生的二次谐波分量。二次谐波分量随着产生应力故障的疲劳试验循环次数的增加而增加。在10万次和20万次循环时，与无应力板相比，二次谐波分量分别增加了约3 dB和6 dB。
Lamb waves are transmitted into pure magnesium plate which is carried out fatigue test and the second harmonic components generated from the plates are detected. Second harmonic components had increased as the number of fatigue test cycles producing the stress faults was increased. At 100 thousand and 200 thousand cycles, second harmonic components had increased by approximately 3 dB and 6 dB respectively compared with an unstressed plate.
