Minimum Effective Cost Design of Composite Cylindrical Pressure Vessels Related to Gun Tubes

摘要

The dimensions of a composite gun tube consisting of a cylindrical liner and a cylindrical jacket of dissimilar materials necessary to endure given internal pressures are determined theoretically. The dimensions are optimized with respect to effective cost which is defined in terms of both material cost and cost per pound of weight to the external system (penalty factor) within constraints imposed on the stress levels reached in liner and jacket through a yielding criterion. Results are presented for a steel liner - glass epoxy jacket composite tube for a variety of costs per pound to the external system. Comparisons are made with respect to minimum weight design and conventional tube designs. (Author)
