A material model was devised for aluminium alloy conductor strands based on own tests.
- el">•
The new model was then applied in FE analyses of the tensile response of conductors.
- el">•
The influence of residual stresses generated during manufacture was investigated.
- el">•
The results from FEA were compared with observations from tests on conductors.
- el">•
Manufacturing history has a large effect on tensile response in the first load cycle.
