Original language name
Noise spectroscopy of mechanically stressed insulating materials
Original language description
After the application of mechanical stress to a solid, cracks are formed and a redistribution of electric charge takes place. The crack faces are charged with opposite charges thus forming a time variable electric dipole or a double-layer. Hence they become sources of an electromagnetic field, which may be detected in the vicinity of the solid in question by means of appropriate sensors. The practical application of this phenomenon is in the diagnostics of non-conducting materials and structures under mechanical stress, and, particularly, for registering the generation and evolution of micro-cracks and other defects in materials and their localization.

Šumová spektroskopie mechanicky namáhaných izolantů
Czech description
Při mechanickém namáhání nevodivých pevných látek dochází k redistribuci elektrického náboje a vzniká elektromagnetické pole. Praktickou aplikací této metody je diagnostika mechanicky namáhaných nevodivých látek.
