SOR-II: A PROGRAM TO PERFORM STRESS ANALYSIS OF SHELLS OF REVOLUTION

Technical Report ·
OSTI ID:4792559
The program solves for the forces, deflections, stresses and strains in thin shells of revolution. The shells may be general surfaces of revolution with variable thicknesses and elastic moduli. This includes the more familiar forms; the circular flat plate, cone, cylinder, sphere, ellipse and tori with circular or elliptical cross sections, for which a simplified input is used. The axisymmetric loadings considered include arbitrary distributions of normal, tangential, and moment surface loadings, as well as edge forces and deflections. The effects of temperature variations in the meridional and thickness directions as well as centrifugal loading due to rotation about the axis and vibration are included. The program will solve and join together up to 10 shells. The additional effects of misalignment, line loads, and elastic supports at the shell intersections are considered. SOR-II numerically integrates the shell equations using a generalized Adams-Moulton method. The integration proceeds along the shell with automatic adjustment of interval size for maximum speed within the limitations of the preset error bounds. The integration error bounds, which may be altered by input, are preset to give for most cases, four significant figure accuracy. To insure optimum results, it is recommended that the maximum length of any one shell not exceed six attenuation lengths. The method used permits solution of problems in which the shell includes the axis of revolution. It also allows step changes in loadings and some shell properties. The timing depends on the number of shells being connected and the accuracy requested. However, an average time of 1.5 min/case was experienced. (auth)
