A Finite Difference Program for Computing the Thermo-Elastic-Plastic Response of Lined Gun Barrels

Abstract

A finite difference computer program for computing the thermo- elastic-plastic response of multi-layered cylinders due to repeated firing loads was discussed at the 27th Conference of Army Mathematicians. The multi-layered cylinder is a representation of a lined gun barrel. The program can accommodate several layers and can compute the transient temperatures and/or the stresses. It has been upgraded to include an initial program which computes heat transfer coefficients, pressures and gas temperatures in the firing cycle for input to the main program. The effect of contact resistance between layers is now included. Results are shown for the behavior of a TZM liner in a steel tube.
