Non Destructive Testing of Body Armor Plates for Structural Integrity

Abstract

These briefing charts present a method for testing the structural integrity of the strike plate portion of body armor plate. An AC voltage will cause the piezoelectric transducer to vibrate and this vibration when coupled to the material being tested will excite a resonant mode in the plate which can then be measured by another transducer. A new plate will have the reference mechanical modes of vibration. Used plate will have a different set of vibration modes due to a different structure. This test configuration will show a profound change of the amplitude of the transmission signal if the plate is cracked or has holes in it.
