Abstract
In this paper, a jerk-dot sensor, which measures the second derivative of the acceleration, is developed. Its capability of detect the local damage in structural members is investigated through lowcycle fatigue tests, which prove its significant sensitivity to the abnormal responses due to the development of macroscopic damages. Further fracture tests are carried out to obtain the correlation between the measured jerk-dot and the crack depth, which suggests that this sensor could provide an early alert before the crack grows up the fatal stage compared with AE sensor and accelerometer.
