Magnetic noise measuring

Project description:
Development of new magnetic noise measuring techniques as a tool of material testing technology (syndicate, 4th member)

Project starting and ending dates:
2005.01.01 - 2007.12.31

Project reg. nr.:

Project summary:
A number of mechanical properties of construction materials can be investigated or classified while applying some empirical or semi-empirical relationship between certain (i.e. time) averaged parameters of magnetic noises. Main objectives of the project syndicate formed by professionals, who gained a lot of experience in measurement methodology, physical basics of noise measurement and processing, was to design and develop tools on the basis of detailed analysis of the total noise spectrum made when performing measurement of acoustic noises or those either produced by fracture or excitation as magnetic noise, with special regard to the latest results of statistical physics. As a result, we want above defined parameters gain acceptance as a tool of material classification technology. Moreover, we also want some statements become confirmed, including our preliminary statement that says: exponents of height and peak area distribution in spectrum of magnetic emission signals differ when ductile or brittle fracture occurs; or regarding other similar relationship discovered in present application. As international professionals also stated, above results are considered as novelty. They will find application in meter device production and distribution as well as in several industries (energy, chemistry, transportation) as classification tool of construction materials.
