Mechanical Engineering : Machine Design - Quiz(MCQ)
In which of the following case stress concentration factor is ignored?
A)
Ductile material under static load
B)
Brittle material under static load
C)
Ductile material under fluctuating load
D)
Brittle material under fluctuating load

Correct Answer : Option (A) :   Ductile material under static load


Explanation : In ductile materials under static load, there is plastic deformation near yielding point and hence redistribution of stresses take place. The plastic deformation is restricted to a smaller area and hence no perceptible damage take place.
