Structural Degradation of a Tank Cannon due to Hole Damage

Abstract

An analysis was undertaken to determine the deleterious effects upon the M256 tank cannon's structural integrity if it were perforated. The analytical study looked at holes ranging in diameter from 1.5 in (3.8 cm) to 4.0 in (10 cm). Two perforation scenarios were modeled: one having a centered through hole and the other with a single hole centered on the cannon's wall. Finite element analysis runs were made to determine the extent of the plastic deformation that resulted from the introduction of the hole. Two locations along the barrel's length were considered: one near the muzzle end and the other at the tube's midsection. The muzzle end exhibited a greater depth of plastic stress with nearly one-third of the gun tube wall going into the plastic regime for the largest hole sizes.
