摘要: Abstract This report contains results of acoustic emission studies on flawed and unflawed specimens aluminum beryllium. Acoustic from the is found to begin at stress levels far below general yield stress. A theoretical model given here indicates that total number signals a specimen containing crack should be proportional fourth power intensity factor obtained sharp-crack fracture mechanics analysis. in disagreement with experimental data single-edge-notched toughness two materials, which indicate varies more like sixth eighth factor. An example show how can used nondestruetively test strength an engineering structure.
