KEYWORDS: Damage Tolerance Analysis, Full-Scale Fatigue Crack Growth
ABSTRACT: The Federal Railroad Administration, with supplemental support from the Railway Progress Institute, contracted with the Association of American Railraods (AAR), Transportation Technology Center, Inc., a subsidiary of the AAR, to conduct a full-scale damage tolerance analysis (DTA) validation test on a tank car using the Simuloader. This is one of five companion reports that detail North American tank car indsuty efforts since 1992 to assess the operating environmnt and apply DTA principles to tank car design. These efforts included: an over-the-road environmental survey, coupon spectrum variable testing, a full-scale fatigue crack growth test, fractographic analysis of the full-scale test car, and DTA analystical model validation and application guidance. This document covers only hte details of the 300,000-spectrum-mile full-scale DTA validation test.
