Abstract
Fatigue life prediction of AA1350-H19 wires of ACSR Tern overhead conductor was investigated. Fatigue test data of plain wires, circumferentially V-notched wires, and wires with transverse hole were obtained for fully reversed axial loading. A three-dimensional fatigue life prediction methodology, based on averaging the stress distribution in a damage zone, was implemented in the commercial finite element-based package Abaqus. The test data from the plain and the V-notched wires were used to calibrate the methodology. Fatigue life estimates of the wires with transverse hole were within factor-of-four boundaries. The results suggest that the fatigue life prediction methodology can be applied to predict the fatigue life of two contacting wires of an overhead conductor.
