60mm M225 Fatigue Test and Burst Test

Abstract

The tube fatigue lab was asked to fatigue test four, 60mm M225 mortar tubes, by applying up to 30,000 cycles to each tube. The purpose was to prove that a 60mm M225 mortar tube was safe to fire should the bore diameter reach 2.421 inches. The current bore diameter limit is 2.411 inches. Laboratory fatigue and burst tests were also used to verify Finite Element Analysis. Each tube was tested at a pressure of 10,080 psi at ambient temperature and the test was halted when the tubes reached 30,000 laboratory cycles. Subsequent to fatigue testing, each tube was pressurized until the tube burst. This report describes the equipment and the methodologies that were used for testing the four M225 60mm mortar tubes and the results of the fatigue test and burst tests.
