Title: Test methodology for tubular components. Volume 1. Fast fracture and lifetime prediction. Topical report, June 1, 1986 to August 14, 1990

Abstract

Improved analytical methodologies were developed such that the fast fracture behavior of silicon carbide (SIC) tubular components subjected to internal pressure, at room and high temperatures, could be predicted from the fast fracture behavior of simple laboratory specimens. Stress distribution and effective volume (area) terms were developed for each specimen configuration to permit accurate strength predictions based on Weibull statistical analysis. Two methods of scaling Weibull strength distributions are discussed. Analytical methodologies were also developed to predict the lifetime of thermomechanically loaded SiC tubes based on realiability analysis conducted on simple laboratory specimens subjected to similar delayed failure modes (e.g., creep rupture mechanism for SCRB210 and slow crack growth (SCG) for SASC).
