fatigue failure Flashcards
1
Q
what is crack propagation?
A
applied stress concentrates on residual material beneath a stress riser and means the number of cycles to failure is much lower than the fatigue strength
2
Q
what is an sn curve?
A
an SN-curve gives information about the number of cycles a material can endure for a given stress level
