Fatigue damage monitoring in 304L steel specimens by an acoustic emission method

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

The aim of this work was to clarify fatigue crack initiation and propagation mechanisms in 304L austenitic stainless steel under different total-strain-amplitudes. A complete process from crack initiation and propagation was recorded by using the acoustic emission method in one hand, and replica method in another hand. The effect of strain amplitude on fatigue crack growth was investigated and a new representation of various fatigue curves associated to various levels of fatigue damage is proposed.
