Influence of propagation distance on the acoustic emission parameters in metal plates Vrije Universiteit Brussel
Metal materials and structures are commonly inspected by the acoustic emission (AE) technique. Any event of crack propagation or corrosion development results in the emission of elastic waves which are captured by sensors on the surface of the material. Study of the AE signal incoming rate, as well as qualitative signal parameters, reveals crucial information on the extent of damage and the cracking mode. Based on laboratory experiments, ...
