Growth Threshold

In order to reduce the time and labor cost, an unattended testing system which can be monitored remotely for fatigue crack growth threshold test was developed. Compliance technique is used to measure fatigue crack length automatically. GSM modem and industrial camera are utilized to realize remote monitoring. Fatigue crack growth threshold test on J2 steel, which is used on the wheel of high-power locomotive, has been carried out with the developed system. The testing process and results demonstrated the safety and efficiency of the system.
