Main Objective

The overall objective of COMET project Phase II is to establish a robust correlation model between coercivity and fracture toughness on real-life samples in order to develop the first prototype of a coercimetry-based fracture toughness assessment solution.

Public Abstract

The strategy for Phase II of the program can be enumerated as follows:

  1. Perform non-destructive tests on actual pipe samples provided by PRCI to obtain more data samples and confirm the correlation between coercivity and fracture toughness.
  2. Complete normalized destructive testing on all samples.
  3. Build a robust empirical correlation model between coercivity measurements and fracture toughness.
  4. Develop a field-deployable prototype and test it with material from PRCI which hasn't been used for destructive tests.
  5. Test the technology on-site at a location determined by U.S. Department of Transportation.
