Abstract

Estimation of local cyclic stress ratio due to confined notch plasticity W.R Locke/ J. Byrne* " Aero structures, Hamble, UK * Department of Mechanical and Manufacturing Engineering, University of Portsmouth, Portsmouth P01 3DJ UK ABSTRACT An FE analysis was used to determine the elastic and elastic-plastic stress distributions at 3 different keyhole notch geometries in compact tension specimens. This enabled an estimate to be made of the local cyclic stress ratio, R^ocai (<7min.ioca/Keywords
