Fatigue Flashcards
1
Q
What causes fatigue
A
Repeated cycles of alternating stresses, eventually causing the metal to develop microscopic cracks
These grow and reach a critical size, causing a large fracture
The material is said to have failed
2
Q
Aircraft mass
A
Greater aircraft mass will cause greater stress and require fewer cycles before failure
3
Q
Weight and fatigue
A
1% increase in weight leads to 5% increase in fatigue life consumption
