Ultra-p: A Portable Nonlinear Ultrasonic Device


Physical Sciences, Chemical Sciences

Focus Area:

Damage Assessment

Social Benefits:

The developed device is portable and is suitable for structural damage assessment of in-service components non-destructively, The device utilizes low frequency ultrasonic transducers in comparison to the available ultrasonic corrosion mapping technique with high frequency, delay line probes, Hence the process is cost effective and less noisy, The developed device overcomes the limitations of existing laboratory based system for higher harmonic analysis of ultrasound based system and the present invention steps towards a portable device with predictive model for determination of probability of failure of air-frame components due to corrosion pitting.
