GLEEM Testing Fixture

Report No. ARL-TN-360

Abstract: A test method was used to develop a process to emplace a refractory metal liner inside a gun tube as a part of an effort at the U.S. Army Research Laboratory to develop an autofrettage gun barrel application. The process consisted of filling the liner with an elastomeric material and then slipping this arrangement into the gun tube. The ends of the liner were plugged with plastic disks, and pressure was applied to the elastomeric material by a load frame. A test fixture was developed to facilitate containment and alignment of the gun barrel during testing. The fixture is described in this report, and preliminary data is provided to show the utility of the fixture.
