Abstract:
1. A method for inspecting a wall of a mechanical structure, comprising: obtaining an infinite response from a calibration sample having a front face, a thickness, and a back wall, by using one or more transducers for transmitting into the calibration sample an ultrasonic wave having a frequency and duration; accessing a user terminal in communication with one or more transducers for transmitting an ultrasonic wave into a mechanical structure to be monitored and for receiving a response signal wave form back from the mechanical structure being monitored; transmitting an ultrasonic wave generated by the one or more transducers into the wall of the mechanical structure being monitored at a time (T), wherein the ultrasonic wave has the same frequency and duration as the ultrasonic wave transmitted into the calibration sample; receiving a response signal wave form back from the wall of the mechanical structure being inspected; and correlating the response signal wave form received back from the wall of the mechanical structure being inspected to the infinite response, thereby creating correlated data from the response signal received back from the wall of the mechanical structure being inspected and the infinite response using a central processing unit in communication with the one or more transducers, wherein said correlated data indicates whether the wall of the mechanical structure being inspected is compromised or damaged.
