Test Your Fatigue Knowledge

Did you know that the number of structural failures due to fatigue is much larger than due to static overload? Managing and preventing problems due to metal fatigue should be considered a key capability of a structural engineer. Do you want to know how your fatigue knowledge is? Do the Fatigue Knowledge Test.

Test Your Fatigue Knowledge

1 / 8

What is the effect of notches compared to unnotched material?

2 / 8

The fatigue life of a structure can be calculated with an accuracy of

3 / 8

What is the stress concentration factor of a circular hole in an infinite sheet under tension?

4 / 8

Fatigue cracks initiate much easier at the surface than in the core of a material.

5 / 8

Fatigue failures are characterized by a large amount of plastic deformation.

6 / 8

What is the effect of mean stresses on the fatigue limit?

7 / 8

Compressive residual stresses at a critical location are favourable for the fatigue behaviour.

8 / 8

The stronger the material, the larger the effect of surface roughness on the fatigue limit
