Abstract

Programs are presented for block loading with determined and random alternation of stress amplitude simulating the service loading spectrum. The results of fatigue tests of straight and bent tubular structural members are presented. It is concluded that low fatigue strength of bent tubular structural members is caused by the unfavorable technological effects of bending these pipes and by warping of the cross section during testing.
