The Challenge
When in-service related damage is discovered how do we determine the critical crack size or the remaining service life of the component.
The Solution
BEASY’s fracture modeling tools were used to create a model of the actual rotor hub and a crack growth analysis was performed using realistic fatigue spectrum loading. An initial flaw located on the inside bore of the lug hole was propagated fully automatically including the transition from a part-through to through thickness crack.
The Value
BEASY provided the capability to obtain accurate (and realistic) fracture mechanics solutions. As a result inspection intervals were improved and better management decisions made with regard to the use of the aircraft.
