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 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 December 2028.

Abstract

Many critical engineering systems, ranging from aircraft engines and power turbines to robotic devices and precision instruments, contain components that interact through friction and contact. These interactions are difficult to model, yet they play a vital role in determining the reliability, efficiency, and durability of such systems. Inaccurate vibration predictions can lead to fatigue, wear, or even failure,…
