METHODS AND SYSTEMS FOR DETECTING FLAWS IN AN OBJECT

摘要

The present application is directed towards systems and methods for evaluating the integrity of objects through non-destructive means. The objects are evaluated for flaws and defects through the use of applied acoustic energy. The applied acoustic energy creates a dynamic response of the object being evaluated to determine the location of any flaws or defects in the object. During excitation, the flaws and defects in a sample object generate heat at the damaged or defective regions through frictional interactions of the discontinuities. A flaw detection system includes, a plurality of acoustic energy sources to excite an object, a camera to record metrics of the response of the object and a processor configured to receive and analyze the response of the object.

主权项

1. A method for detecting flaws in an object, the method comprising:
determining a location on the object to place an acoustic energy source; applying a static preload between a contact point of the acoustic energy source and the object; applying acoustic energy to excite the object; recording a thermal response of the object to the application of acoustic energy; and analyzing the thermal response to identify flaws within the object.
