The objective of this study is to determine theoretically, the dimensions of a composite gun tube consisting of a steel liner and a composite jacket made of steel filaments embedded into an epoxy matrix when subjected to an internal pressure. The economic success of these tubes when compared with conventional tubes is investigated. The dimensions of the composite tube are optimized for minimum weight with the restriction that the applied stresses in both liner and jacket does not exceed stress levels determined by a yielding criterion. The economic success is obtained by considering the various factors which determine the tube's cost and the relationship between the tube's weight, performance, and cost. (Author, modified-PL).

Pressure vessels are closed containers designed to hold gases or liquids at a pressure substantially different from the ambient pressure. They have a variety of applications in industry, including in oil refineries, nuclear reactors, vehicle airbrake reservoirs, and more. The pressure differential with such vessels is dangerous, and due to the risk of accident and fatality around their use, the design, manufacture, operation and inspection of pressure vessels is regulated by engineering authorities and guided by legal codes and standards. Pressure Vessel Design Manual is a solutions-focused guide to the many problems and technical challenges involved in the design of pressure vessels to match stringent standards and codes. It brings together otherwise scattered information and explanations into one easy-to-use resource to minimize research and take readers from problem to solution in the most direct manner possible. - Covers almost all problems that a working pressure vessel designer can expect to face, with 50+ step-by-step design procedures including a wealth of equations, explanations and data - Internationally recognized, widely referenced and trusted, with 20+ years of use in over 30 countries making it an accepted industry standard guide - Now revised with up-to-date ASME, ASCE and API regulatory code information, and dual unit coverage for increased ease of international use
