DOI: 10.1016/j.ijfatigue.2018.08.025
Abstract: Abstract Microstructural investigations and mechanical fatigue tests with in situ optical strain field measurement were performed on unnotched, notched, and bending AZ31B magnesium specimens. Twinned and twin-free regions are clearly delimited and compressive strain within… read more here.
