It is desired to incorporate advanced materials in gun barrels to increase service life, enable advanced propellants to provide for increased kinetic energy, and decrease system weight. Ceramic materials possess superior erosion resistance, high temperature performance, and lower density than steel making them attractive candidates as gun tube liners. A new design approach is necessary to address the large variability in strength, one that is probabilistic instead of deterministic in nature. Models derived to incorporate this new approach have been developed and are being used to provide an understanding of the optimal geometry, sheathing material requirements, and pre-stress levels for system success.
