This publication contains papers presented at the symposium Fracture Resistance Testing of Monolithic and Composite Brittle Materials held in November of 2000. The symposium was sponsored by ASTM Committee C28 on Advanced Ceramics.
The papers presented at the symposium fell into four themes: Implications for Design and Testing; Fracture Toughness Standardization; Crack Growth Resistance; and Unique Materials and Environmental Effects. Although three of the themes are relatively broad and papers representing a variety of subtopics were presented, the session on Fracture Toughness Standardization was relatively focused.
The papers published in this collection summarize the latest standard methods for the measurement of fracture toughness, slow crack growth, and biaxial strength, and indicates new areas for fracture toughness test method development and standardization: testing of complex materials, elevated temperature measurement, and R-curve measurement. Indications were also given during the symposium that test method development is needed in the areas of elevated temperature biaxial strength measurement and slow crack growth by static loading.
Specific topics covered by the papers published in this collection include:
- ceramic fracture toughness characterization
- fracture resistance, silicon nitride single edge notched beam (SENB) specimens
- toughening mechanisms in polycrystalline ceramics and ceramic-based composites
- crack-deflection tests
- fractography
- fractal analysis
- functionally graded material
- residual stress
- issues of fracture for materials with large grains existing in small grain matrix
- Titanium carbonitrides (TiCN)
- single edge V-notched beam (SEVNB) method
- dynamic fatigue
- slow crack growth
- brittle fracture
- multiaxial strength
- chevron-notched beam (CNB)
Engineers and scientists working in ceramics development and use will find the information contained in this STP useful for understanding test methods, modeling, and limitations of ceramic materials.
