Abstract : Fuse tests were conducted on the fuse components of the Antipersonnel Obstacle Breaching System (APOBS) to evaluate three slightly varied spring designs of the u-shaped stainless steel retaining spring samples. Few failures occurred with the spring samples. With one particular spring design, popping out occurred during the tests; whereas, the spring samples of the other two designs did not fail. A material investigation was performed to determine why one spring design would cause occasional failures during the fuse tests. The primary cause of a few spring failures was due to the fact that the failed spring design did not allow full engagement of the spring in the fuse components of the APOBS.
