COMPUTER TOMOGRAPHY AND IMAGE PROCESSING FOR ANISOTROPIC DAMAGE DETECTION ON FIBRE REINFORCED PLASTICS
Abstract
Volume computer tomography (VCT) is an established non destructive testing method, which offers the possibility to capture internal structural damage three-dimensionally. Thus, the complex failure mechanism of endless fibre reinforced plastics can be visualized and classified into the basis failure modes: fibre failure (FF) and inter fibre failure (IFF) taking different loading types into account: tension, compression and shear. A new approach analyzes these VCT data in combination with image processing algorithms to identify the anisotropic damage parameters of pre-damaged CFRP tubes in dependence of the real arising failure modes. Thereby the kind, size and orientation of the detected failure will be estimated automatically. The software was developed on basis of the MATLAB environment and provides input data for a subsequently finite element analysis in ANSYS.
