Question 63
MTNAT2 marksNeeds review
A large rectangular component is undergoing fully-reversed cyclic loading, and the component is known to grow the dominant fatigue crack from the outer surface. If the stress amplitude (
) is 100
and the critical stress intensity factor
of the material is 50
then the crack length at which the component will fail catastrophically is _____
.
(Round off to one decimal place)Given: The geometric factor
for this loading condition is 1.12.Log in to check the answer
