Advances in the Study of the Mechanical Behavior of Materials

Abstract

The design of high performance aircraft engines requires the development of reliable life-predication methodology to aid in the evaluation and safety of the critical gas-turbine engine components. A comprehensive multi- task research and development program was conducted to establish a sound life- prediction methodology. The program consisted mainly of : (1) Experimental investigations and analytical modeling of crack growth behavior; (2) Experimental investigation of mechanical properties and performance characteristics of structural materials; (3) Environmental effect on elevated temperature mechanical behavior; and (4) Development of test techniques, upgrading, and maintenance of the AFWAL/MLLN Mechanical Test Facility. Keywords: Automated test control; Material characterization; Nickel base superalloys; Laser interferometry; Electric potential.
