Abstract
The link between dissipated energy in a cyclically loaded AISI 316L stainless steel and its microstructural changes is investigated. After a brief introduction to energy dissipation in materials, the experiments devised to investigate if different microstructures, resulting from different heat treatments, has a measurable effect on the dissipated energy are detailed. The data processing procedure and some preliminary results are described. Future work aimed at characterising the dissipative heat source in welds is presented.
