Free-Cutting Brass Breakaway Couplings

The objective of this research project is to evaluate the design of a free-cutting brass breakaway coupling device for use in supporting poles. These devices could be used to replace the currently used aluminum or steel couplings, and potentially save the Illinois Department of Transportation (IDOT) significant resources. An application process is also underway for a patent. The review, and as- needed or suggested modifications to this device, will be based on the results of physical testing and of calibrated finite element analysis (FEA). The physical testing will be contracted out by the University of Illinois, Urbana-Champaign (UIUC) research team, while the FEA will be performed by UIUC researchers.
