Fatigue due to repetitive strain is the leading cause of failure in metal components and structures, but new research shows how crystalline structures called nanotwins can slow the accumulation of ...

Fatigue life is a key concern in welded-steel frames for mobile equipment that experience large and varying dynamic loads. For engineers who design welded-steel structures subject to dynamic loading, ...

Engineers have identified a fundamental deformation mechanism that can be leveraged to greatly enhance the fatigue properties of metals, opening the door to a new strategy for designing ...
