Fatigue Life Assessment of 155-mm M284 Cannon Tubes

Abstract

Benet Laboratories has the responsibility for safe service life (fatigue) testing of cannon system components. This safe service life evaluation is accomplished by conducting constant amplitude fatigue tests using hydraulic oil as the pressurized medium, One such cannon component that requires testing is the gun tube. After each tube has received the required number of live fire rounds necessary to generate heat check cracking in the bore, it is brought to the laboratory for final hydraulic fatigue testing. A sample size of seven 155- mm M284 gun tubes was hydraulically fatigue tested to failure at Benet Laboratories to determine the safe service life for the weapon. This report contains the results of the fatigue tests conducted on the subject tubes, including material inspections, failure lives, and the resulting safe service life.
