Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 31 August 2029.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 December 2029.

Abstract

Fatigue refers to the mechanical failure of materials subjected to repeated cyclic loads. It occurs in all materials including metals and alloys, and is a significant limitation that affects all engineering structures and devices (both structural and functional). It is a common cause of failure (and accidents) in devices including computers, cars, bridges and airplanes, and thus a significant economic, societal and…
