Abstract

This investigation was initiated as an attempt to determine experimentally the effect of residual stresses on fatigue strength. These stresses were produced by cold-bending specimens of structural steel flat in the strong direction, and unloading. Holes were drilled in the central, elastically strained region, and the specimens tested in fatigue under an applied fluctuating load.
This paper presents-
(a) the moment curvature relationships obtained during bending, the number of specimens (fourteen) being sufficient to provide some indication of the consistency of behaviour into the partially plastic range;
(b) a comparison between estimated and measured cold-bend residual stresses;
(c) a comparison between the fatigue strengths of specimens with and without artificially induced residual stresses.
The number of fatigue tests was small, but indicated no detrimental effect due to residual stresses of the order of 18 kips-sq. in.
