摘要

It was proposed to seek experimental confirmation of theoretical predictions thatthe opening and closing of cracks in structures during vibration can provide dramatic qualitative and quantitative signatures at crack presence, even if the crack is very small. Cracked and uncracked laboratory-sized beams were driven by superpositions of two harmonic loads. Responses at the difference or sum of the
