COMPARISON OF APPROXIMATE SOLUTIONS OF THE THERMOELASTIC PROBLEM OF THE THICK-WALLED TUBE
Abstract
The stress distribution in a thick-walled, circular cylindrical tube subjected to a steadystate temperature gradient across the tube wall is calculated, taking into account the variation with temperature of the elastic and thermal properties of the material. The calculations are made by 5 methods: (1) by electronic digital computer; (2) by assuming an incompressible material; (3) by assuming a temperatureindependent material and using the average properties of the material; (4) by using the weighted-average properties of the material; and (5) by using a higher order approximation. Good agreement is found when high temperature levels do not persist over large portions of the tube. When the latter is the case, only Method 5 gives better than a qualitative picture of the stress distribution. (Author)
