Device and method for setting stress corrosion cracking monitoring indicating parameters using an acoustic emission sensor

Abstract

According to one aspect of the present invention, a device for setting a reference monitoring parameter for detecting stress corrosion cracking using an acoustic emission sensor includes: a database configured to store information on a first acoustic emission signal generated during a tensile test, a second acoustic emission signal generated under a first condition prior to the formation of stress corrosion cracking, and a third acoustic emission signal generated under a second condition during the formation of the stress corrosion cracking, a parameter derivation unit configured to derive a first monitoring parameter related to actual crack generation from the information on the first acoustic emission signal, and to derive a second monitoring parameter unrelated to stress corrosion cracking from the information on the second acoustic emission signal, and a monitoring parameter setting unit configured to set a third monitoring parameter, derived from the information on the third acoustic emission signal using the first and second monitoring parameters, as a reference parameter for detecting stress corrosion cracking.
