On the project

Description in English
Main project aim is enlargement and specification of description and fact-finding content of acoustic emission signal by means of new analytical procedure to processing digitise signal (WT, STFT and so on). Modify of modern commercial software processingsignal will necessary use for these purposes. Applications of acoustic emission method will use at different branch of civil engineering on especially thin-walled structures. These applications make possible detachedly determine peace active failure structure on basis following rise and diffusion cracks near static or dynamic loading. New process application to plotting measured acoustic emission signals on practical thin-walled construction elements and materials will be observed. The non-destructive testing material with exploitation of acoustic emission phenomenon is one of very perspective non-destructive methods. New knowledge from analyses signal domain is also necessary to easy and clear interpretation especially of acoustic emi
