Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research was to understand the room temperature and high temperature behavior of brittle materials such as in situ toughened ceramics, glasses and intermetallics as the basis for developing life prediction and test methodologies. A major objective was to understand the relationship between microstructure and mechanical behavior within the bounds of a limited number of materials. A second major objective was to determine the behavior as a function of time and temperature. Specifically, the room temperature and elevated strength and reliability, the fracture toughness, slow crack growth and the creep behavior. These results will provide input for parallel materials development and design methodology programs. Resultant design codes will be verified. A summary of the accomplishments that occurred under this program is given.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the major challenges involved in the use of ceramic materials is ensuring adequate strength and durability. This activity has developed methodology which can be used during the design phase to predict the structural behavior of ceramic components. The effort involved the characterization of injection molded and hot isostatic pressed (HIPed) PY-6 silicon nitride, the development of nondestructive evaluation (NDE) technology, and the development of analytical life prediction methodology. Four failure modes are addressed: fast fracture, slow crack growth, creep, and oxidation. The techniques deal with failures initiating at the surface as well as internal to the component. The life prediction methodology for fast fracture and slow crack growth have been verified using a variety of confirmatory tests. The verification tests were conducted at room and elevated temperatures up to a maximum of 1371[degrees]C. The tests involved (1) flat circular disks subjected to bending stresses and (2) high speed rotating spin disks. Reasonable correlation was achieved for a variety of test conditions and failure mechanisms. The predictions associated with surface failures proved to be optimistic, requiring re-evaluation of the components' initial fast fracture strengths. Correlation was achieved for the spin disks which failed in fast fracture from internal flaws. Time dependent elevated temperature slow crack growth spin disk failures were also successfully predicted.
