AGARD (Advisory Group for Aerospace Research & Development) Engine Disc Cooperative Test Programme,

Abstract

This report describes the initial results of an AGARD test programme on fatigue behavior of engine disc materials. The first phase of this programme, the Core Programme, was aimed at test procedure and specimen standardization and calibration of the various laboratories. A detailed working document has been prepared and is included in this report. It describes the testing fundamentals and procedures and includes the analysis procedures used for handling the test data. Fatigue crack initiation and propagation testing was performed on Ti-6Al-4V material under room temperature and constant amplitude loading conditions using four different specimen designs. All results were statistically analysed for possible significant differences in material behaviour due to disc processing variables, specimen location in the disc or testing laboratory. Titanium alloys, Aluminium; NATO. (MJM)
