Abstract
This work provides a time domain approach to detect stress changes in hollow cylinders using low frequency ultrasound guided waves; the proposed scheme makes uses of the subtract method for stress level estimation. Residuals are generated by signal subtraction of the reference signal, at nominal condition, from the current signal. The stress condition is detected when the RMS of the residual goes above certain threshold. A simple supported hollow cylinder is utilized in this research and the dif...
