Hildebrand, Advanced Calculus for Applications, 2nd Edition, Prentice-Hall, Inc., Englewood, NJ, 1976, pg. 447, equations 38-44. Analysis Type(s): Thermal Analysis (ANTYPE = 0) Element Type(s): Axisymmetric-Harmonic 8-Node Thermal Solid Elements (PLANE78) Input Listing: vm160.dat Test Case A long solid cylinder has a harmonically-varying temperature load along its circumference represented by a cosine function with positive peaks at Θ = 0° and 180° and negative peaks at Θ = 90° and 270°. Determine the temperature distribution along the radius at Θ = 0 and Θ = 90°. Figure 160.1 Solid Cylinder Problem Sketch Material Properties k = 1 Btu/hr-ft-°F Geometric Properties ro = 20 ft Loading To = 80°F Analysis Assumptions and Modeling Notes The axial length of the model is arbitrarily chosen to be 5 ft. The temperature loading is applied as a symmetric harmonic function (Mode 2) around the periphery of the cylinder. To obtain the theoretical solution, equations 43 and 44 i...
