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

This award supports research to develop a novel wave-based approach to investigate and analyze systems constructed with mechanical joints, such as structural frames used commonly in advanced manufacturing, as well as buildings, bridges, vehicles, and aerospace structures. The wave-based models constructed will be highly efficient yet capable of capturing complex nonlinear response, and will yield valuable…
