Fatigue failure in engineering materials

Hi all,
I need to write about fatigue failure in materials. I need to say, what it is, explain with an example what it is, stages, stress applied over and over, stress cycles and positive and negative stresses.

Can anyone help me please, im really lost on this one.

Thanks.

I'm not great at explaining but these two video will help you answer your question:

They are similar but the first one give an engineering approach.
