Roark, W. C. Young, Formulas for Stress and Strain, 5th Edition, McGrawHill Book Co., Inc., New York, NY, 1975, pg. 585. Analysis Type(s): Coupled-field Analysis (ANTYPE = 4) Element Type(s): 3-D Coupled-field Solid Element (SOLID5) Input Listing: vm33.dat Test Case A long thick-walled cylinder, initially at a uniform temperature To, has its outer radius temperature raised at a constant rate of 1.0°/sec to temperature Tf. After a steady state of heat flow has been reached, determine the tangential stress at the inner and outer surfaces. Display the outer-to-inner surface temperature difference and the tangential stress as a function of time. Figure 33.1 Cylinder Problem Sketch ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–82 VM33 Material Properties E = 30 x 106 psi υ = 0.3 α = 8.4 x 10-6 in/in-°F k = .000625 BTU/sec in-°F ...
