Fracture Detection by Electro-Ultrasonic Spectroscopy

Popis výsledku v původním jazyce

This paper describes the possibility to verify the electro-ultrasonic spectroscopy method validity. This new approach is based on the combined usage of two modern nondestructive testing methods, the electro-ultrasonic spectroscopy and the diagnostics ofmechanically stressed solid dielectric materials by the electromagnetic (EME) and acoustic (AE) emission signals. The granite sample was measured by the electro-ultrasonic spectroscopy. Then mechanical load (provided by hydraulic press) was applied on this sample. Generally, an application of mechanical stress leads to micro-cracks formation in stressed solid dielectric materials. Cracks generation is accompanied by generation of the electromagnetic (EME) and acoustic (AE) emission signals, which can bemeasured by appropriate sensors. Continual measurement and real-time processing and evaluation of these signals can be used for quantitative sample damage estimation. After mechanical load application the sample measuring was conducted o
