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

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

3 / 8

What is decisive for fatigue?

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

The stress concentration factor of a hole in a finite width sheet loaded in tension is larger than the stress concentration factor in an infinite sheet.

8 / 8

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