Using Acoustic Emission in Fracture Monitoring of Cementitious Composites

Popis výsledku v původním jazyce

In order to predict the mechanical behavior of a material during its service life, it is important to evaluate its mechanical response under different types of external stresses by studying the initiation and development of cracks and the effects induced by damage and degradation. The non-destructive technique of analysis of acoustic emission, especially with source location and full wave-form analysis, provides excellent results on detecting and identifying initiations sites, cracking propagation and fracture mechanisms of polymer matrix composite, ceramic materials and rocks. For this study, loading tests in two different configurations were provided on specimens of same material and geometry. The significant AE features were monitored during each test and also locations of each AE event were estimated. Results of AE analysis are compared with a finite element analysis of the stress distribution and crack propagation within the specimens.
