Book excerpt: The objective of this program was to establish a method for predicting the lifetime reliability of structural ceramic materials in high temperature applications. Fast fracture and stress rupture data were collected on two materials, a sintered silicon nitride and a lithium-aluminum-silicate. The fast fracture data was presented graphically in the form of Weibull plots of percent failed versus failure stress. Stress rupture results were presented in tabular form. Photo micrographs were presented to illustrate the fracture surfaces of fast fracture and stress rupture failures. A program of specimen development was conducted. The objective of the program was to develop processing techniques to make it possible to fabricate integral shaft spin disks suitable for hot spin testing as stress rupture specimens. The hot spin disk stress rupture results were to be used to correlate experimental time dependent failure results with analytical time dependent failure results.

This book was released on 1982 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: A complete set of thermal conditions, mechanical loads, geometry as well as thermal, elastic, fast fracture, and time dependent material properties was furnished by AMMRC for the hub of a gas turbine disc. A finite element computer model was prepared for the disc from this data. The temperature and stress distributions, the fast fracture and the time dependent reliabilities were calculated. The results were presented in iso-stress and iso-thermal plots and in graphical data. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: A rotating disc was designed to fail due to time dependent mechanisms. Several discs were fabricated and a previously existing test rig was developed to test the discs at the design conditions. A successful calibration test was conducted at the design condition of 2300 deg F rim temperature and 50,000 rpm. The disc failed after eight and one-half hours of steady state testing indicating that the design was successful, since the failure was due to a time dependent mechanism. (Author).

Download or read book Probabilistic Aspects of Life Prediction written by W. Steven Johnson and published by ASTM International. This book was released on 2004 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: As fatigue and fracture mechanics approaches are used more often for determining the useful life and/or inspection intervals for complex structures, realization sets-in that all factors are not well known or characterized. Indeed, inherent scatter exists in initial material quality and in material performance. Furthermore, projections of component usage in determination of applied stresses are inexact at best and are subject to much discrepancy between projected and actual usage. Even the models for predicting life contain inherent sources of error based on assumptions and/or empirically fitted parameters. All of these factors need to be accounted for to determine a distribution of potential lives based on combination of the aforementioned variables, as well as other factors. The purpose of this symposium was to create a forum for assessment of the state-of-the-art in incorporating these uncertainties and inherent scatter into systematic probabilistic methods for conducting life assessment.
