Abstract: Systems and methods for monitoring plastic deformation of a structural material are provided. An acoustic wave actuator is configured to generate acoustic wave signals to be propagated within the structural material and is in-situ fabricated on the structural material at a first location. An alternating current (AC) electric signal source drives the acoustic wave actuator to generate the acoustic wave signals at a predetermined frequency. One or more acoustic wave sensors detect the acoustic wave signals generated by the acoustic wave actuator and propagated within the structural material. More particularly, the acoustic wave detectors are configured to detect both fundamental and second harmonic acoustic signals at the predetermined frequency. The acoustic wave sensors are in-situ fabricated on the structural material at one or more second locations.
