Answer #1

Answer-

Material fatigue is a phenomenon where structures fail when subjected to a cyclic load. This type of structural damage occurs even when the experienced stress range is far below the static material strength.

why an engineer should understand the process of fatigue

Because of

Fatigue is very sensitive to stress, and ensuring the accuracy of load and stress estimates is an important step in fatigue engineering so engineer should aware about the fatigue.

after knowing the fatigue strength of a structure an engineer improve and revise the design criteria

The magnitude and distribution of stresses caused by applied loads provide input to fatigue analysis and also reveal opportunities for design improvements.

Realistic problem

The realistic problem is associated with structure which is subjected to cyclic loading

examples

-Highway payment

- flyover

- Bridge
