Dear all,

As per WMTR, the surface finish of the fatigue specimens used in the NASA projects has an average roughness (i.e., Ra) of 0.2 ┬Ám.

We can also achieve this by using our hand polishing technique. So, it is highly recommended to polish all the NASA specimens for which we are planning to generate HCF curves here at Auburn.

Thank you

Sincerely,
