ASPECTS OF RELIABILITY UNDER CONDITIONS OF ELEVATED TEMPERATURE CREEP AND FATIGUE

Abstract

Guidelines for developing techniques for the prediction of fatigue and creep failure of supersonic aircraft structures. The solution of the problem of attaining adequate safety and reliability in supersonic aircraft structures operating under conditions under which the damaging effects of cycle sensitivity (fatigue) and time-sensitivity (creep) of the structural material combine in gradually reducing the resistance of the structure requires the de development of simplified procedures for the evaluation of the combined damage accumulation, which embody both the physical and probabilistic as aspects of design. The present report attempts to develop the basis for an approach to the solution of this problem, for which no adequate experimental mental information exists at present. One of its purposes is to provide the guidelines for the planning of tests and experiments, the results of which would be relevant for structural design.
