Abstract: The reliability of microfocus x-radiography and scanning laser acoustic microscopy for detecting microvoids in silicon nitride and silicon carbide was statistically evaluated. Materials and ...

Abstract: Computed tomography (CT) is a powerful evaluation tool for advanced propulsion engine materials and components. CT uses X-rays nondestructively to produce images of two-dimensional slices or planes ...

Abstract: A new approach to characterizing oxidation damage in ceramic matrix composites using ultrasonic techniques is proposed. In this approach the elastic constants of the composite are determined ...

Abstract: This paper addresses the application of ultrasonic methods to damage assessment in ceramics and ceramic matrix composites. It focuses on damage caused by thermal shock and oxidation at elevated ...

Abstract: The goal of this paper is to show the potential of fuzzy sets and neural networks, often referred to as soft computing, for aiding in all aspects of manufacturing of advanced materials like ...
