Abstract : The work of the late U.S. Army Benet Laboratories engineer David P. Kendall encompassed a broad range of design and analysis of high pressure vessels for use as cannons. He used classic results from research in engineering mechanics to develop descriptive expressions for limiting pressure, autofrettage residual stresses and fatigue life of cannon pressure vessels. Three types of analysis are described in this paper to validate Kendall's design procedures: 1) Yield pressure tests of cannon sections compared with a yield pressure expression; 2) Autofrettage hoop residual stress measurements by neutron diffraction in cannon sections compared with expressions; 3) Fatigue life tests of cannons following proving ground firing and subsequent laboratory simulated firing compared with Paris-based fatigue life expressions that include post-test metallographic determination of the initial crack size due to firing.
