High-Sensitivity Non-Destructive Evaluation/Testing Method for the Detection of Defects in Structures using the Geometric Phase of Acoustic Waves

Case ID:

This novel, highly sensitive non-destructive testing method analyzes the spacial behavior of acoustic waves to detect cracks and defects in objects and structures, with applications across many industries. This method’s sensitivity allows it to detect even slight flaws and defects, and to identify cracks through topographical complexities like welds and bends. Complexities like these can cause extraneous propagation in waves used for non-destructive testing, creating interference that can hide cracks from many current non-destructive testing methods. This method is less affected by that interference and can detect cracks that could otherwise go unnoticed. 

As infrastructure and technology advance, the complexity of products and structures become more and more complex. To ensure their reliability and structural integrity, more advanced non-destructive testing methods are needed. Non-destructive testing is the evaluation of objects for flaws and cracks without causing damage in the testing process. Many current non-destructive testing methods are ineffective around welds, bends, and other structural complexities, and often miss small defects and perturbations. This method’s high sensitivity allows for more precision in crack detection even in complex objects, ensuring a higher level of safety of technologies across a variety of industries.
