Effects of Pressure and Thermal Loadings on a Thin Plating Inside a Thick Tube.

摘要

Stress distribution in a thin layer of plating on the bore surface of a thick tube is studied based on the linear theory of elasticity. Several simple mathematical models are used to represent a variety of material and loading conditions. Results from these simple mathematical models indicate that the chrome plating in a gun tube is very likely to crack. Relative mechanical properties of plating materials and tube materials are discussed in order to reduce the stress level in the plating. (Author)
