Impact Damage and Erosion of Ceramics and Composites.

Abstract

Studies of the mechanical strength of ceramics were conducted. These range from studies of toughness to identation fracture, thermal shock and erosion. The central theme of this report concerns the study of those facets of mechanical behaviors that influence the structural integrity of ceramic components. Specific topics include: On the Grain Size Dependence of Strength; Martensite Transformations in Zirconia--Particle size effects and toughening; Quantitative Studies of Thermal Shock in Ceramics Based on a Novel Test Technique; Toughening of Ceramics by Circumferential Microcracking; Residual Stresses and Microcracking Induced by Thermal Contraction Inhomogeneity; A Simple Method for Adhesion Measurements; The Martensite Crystallography of Tetragonal Zirconia; Wear Mechanics in Ceramics; and Particle Size Distribution Effects on Solid Particle Erosion in Brittle Materials.
