THERMAL STRESS ANALYSIS OF SINGLE-LAYER AND SOFT-BONDED DOUBLE-LAYER SHELLS OF REVOLUTION.
Abstract
Thermal stress problems for single-layer and soft-bonded double-layer shells of revolution are solved by first obtaining mechanically-equivalent loads for a temperature distribution and then solving for deflections and stresses by using SABOR 4 and SABOR 5, which are, respectively, computer codes for the deformation and stress analysis of thin elastic single-layer and soft-bonded double-layer shells of revolution subjected to axisymmetric and/or asymmetric mechanical loadings. Two methods of obtaining equivalent loads for a given temperature distribution are described. One method is based upon equilibrium conditions and used the shell equilibrium equations to obtain equivalent loads; this method has been labeled the 'Hybrid Method.' The second method derives equivalent loads entirely and consistently by variational methods; this method is termed herein the 'Variationally Consistent Method.' Both methods are compared by means of an example problem and are found to produce identical results. However, the 'Hybrid Method' is found to be more convenient from a computational standpoint and is therefore chosen for solving thermal stress problems.
