Abstract

This paper describes the development of infra-red imaging methods to visualize and monitor damage evolution in metallic alloys. Imaging is performed in-situ during tensile and notched tensile experiments at the microstructural grain level. Specimen preparation and imaging techniques are described. The results are anticipated to guide and improve alloy-specific damage evolution constitutive models to enable improved deformation and failure predictions.
