How Boeing Tests Aircraft Structural Fatigue
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 ...
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 ...
A research team at Drexel University's College of Engineering, led by Professors Ahmad R. Najafi, Jonathan Awerbuch, and Tein-Min Tan of mechanical engineering and mechanics, has developed a new way ...
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 ...
That hybrid design both slowed fatigue-driven delamination and enabled in-place repair, confirming that repeated healing of the same crack zone is achievable under controlled fatigue loading. A third ...
An overview of fatigue failure and how it affects mechanical systems. How FEA software enables engineers to predict fatigue failure points on structural designs, before the manufacturing process. From ...
