Paper Abstract

Computed tomography (CT) data has the ability to provide qualitative and quantitative data on composite materials. The focus of this paper will be on the specification and development of qualitative and quantitative analysis tools for he evaluation of engineering components made from metal- matrix composite materials. Qualitative tools include 2D and 3D visualization tools. Quantitative tools include segmentation methods that can output to commercial finite element, micromechanical, and/or continuum damage model software for evaluation of composite materials and components. The linkage of CT data with engineering analysis methods provides the engineering community the ability to do a complete structural analysis on an as-manufactured component rather than solely on an as-designed component. With this capability, extensive effect of defect studies can be performed to determine the effect of manufacturing anomalies on part performance. This will provide a truly nondestructive evaluation capability for engineering structures.
