Research of the Damage and Failure Processes of Composite Materials Based on Acoustic Emission Monitoring and Method of Digital Image Correlation

Abstract:

The work presents an analysis of the methodical questions of the digital image correlation and acoustic emission application for studying damage accumulation process in composites. The research included tensile mechanical tests on flat samples with a hole. According to the acoustic emission data the localization graphs and the peak amplitude and frequency distributions were plotted. Additionally, the analysis of inhomogeneous deformation fields was made by non-contact three-dimensional digital optical system Vic-3D. The optimal parameters of post processing were selected.
