INVESTIGATION OF HIGH STRENGTH STEELS UNDER HISTORY PROGRAM FATIGUE, PART I.

Abstract

As the first high strength steel in a long range research program on the fatigue performance of such steels in aircraft structures a 0.15% C, 1.12% Cr, 3.69% Ni and 0.67% Mo steel of tempered massive martensite structure (sigma sub U = 120-125 kp/sq mm) was investigated in a six bar fatigue test bed under a History Program loading using both notched and unnotched fatigue specimens. The applied fatigue program simulates the service history of the VENOM fighter plane under the operational and gust conditions of Switzerland. (Author)
