"Fatigue Stritations & beach marks"

Question:

"What is the difference between fatigue stritations & beach marks do they have any similarities and how are they used in fracture analysis"

Answer:

Fatigue striations are microscopic features on a fatigue fracture surface that identify one propagation cycle of a fatigue crack. They are not always present and can only be seen under a scanning electron microscope. Beach marks (also sometimes clamshell marks) are macroscopic fatigue features marking an interruption of some sort in the fatigue cracking progress. Both features are used to identify fatigue fractures. Fatigue striations can also be used to estimate number of cycles, etc.
