Metal alloys crack and fail through a mechanism called "fatigue" when repeatedly loaded and strained. While it is well known how to design alloys to withstand static loads and pressures, it is very ...

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 ...

Inside the massive testing hangars across Seattle and Everett, the world's biggest jetliners are turned into mechanical lab rats. Hydraulic actuators yank their wings skyward, compressors simulate ...

Illinois Grainger 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 ...
