Acoustic Emission and Destruction of Inelastically Strained Metal
Source abstract
Abstract
The results of experimental acoustic emission (AE) studies on the stepwise character of deformation and fracture in the uniaxial tensioning of steel specimens are presented. True “stress–residual strain” plots and parameters of the accompanying AE are analyzed in order to determine the characteristic points of the transition of the defect accumulation process from one stage to another. Based on the integral characteristics of the flow of AE events, a method for the detection and quantitative assessment of metal fracture (loosening) under mechanical loading is proposed; this method can be directly used in diagnostics of the prefailure condition of materials.
