Acoustic Emission During Tensile Deformation and Fracture of Nuclear Grade Aisi type 304 Stainless Steel Specimens with Notches

摘要

Acoustic emission generated during tensile deformation and fracutre of nuclear grade AISI type 304 stainless steel specimens with notches has been studied. The extent of acoustic activity generated depends on notch tip severity, notch tip blunting and tearing of the notches. The equation N=AK~m applied to the acoustic emission data of the notched specimens has shown good correlation. Acoustic emission technique can be use to estimate the size of an unknown notch.
