Abstract

In this multilayer vessel investigation, the size of a gap is defined in terms of its circumferential arc length and maximum radial height. The effects of imperfect contact on prestresses are obtained, in terms of the size of the gap, by calculating the stresses sustained by the layer in order to bring the layer in perfect contact with the next layer. A method is proposed to calculate, for a given size gap, the necessary reduction in operating pressure in order to maintain the original factor of safety. For a given tolerance in safety factor and the allowable stress, a method is described to calculate the maximum size of a gap that would not compromise the integrity of the wrapped vessel.
