Alenia Aeronautica has delivered two laser-welded Airbus A380 centre fuselage panels to Airbus's Nordenham-Hamburg factory for fatigue testing. The test will evaluate laser welded and conventionally ...

EPRI (Electric Power Research Institute) reports that 7FA gas turbines have a rotor life of about 144,000 hours, or 5,000 starts. The primary life-limiting factor is high cycle fatigue cracks ...

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 ...

In a first for the construction industry, researchers have developed a virtual vibration test rig (VTR) capable of simulating the fatigue life of dozer push arms with unprecedented accuracy. This ...
