Detection of crack formation in materials using electric emission
Abstract
A technique for detecting the beginning of crack propagation in materials is described. The method is based on the fact that crack formation is accompanied by varying electric fields (Electric Emission). To detect these fields, a special type of gauge has been developed. The investigations reported here demonstrate the connection of Electric Emission to crack formation for the materials glass, concrete and ceramics.
