Mechanical parts are more frequently subjected to cyclic loads than solely static loads. Fatigue issues are commonly observed in turbine blades, aerospace components, locomotive systems, large ...

Novel identified mechanisms of dynamic plastic delocalization in metal enabled by competing deformation mechanisms to significantly enhanced fatigue performance of metallic materials. Metal alloys ...

Studying fatigue cracks at the nanoscale: Sandia National Laboratories researcher Ryan Schoell uses a specialized transmission electron microscope technique developed by Khalid Hattar, Dan Bufford and ...

In August 2023, researchers at Sandia National Laboratories directly observed nanoscale fatigue cracks in pure platinum and copper films closing on their own under cyclic loading in a vacuum. The ...
