Unformatted text preview: of elements (15) is modeled through the thickness such that an accurate
thermal transient and nodal stress results are obtained.
Symmetric structural boundary conditions are used at the radial and bottom planes. Since the cylinder being
modeled is long, nodes at z = h are coupled in UZ to enforce a constant axial strain condition. The reported values
at t = 430 sec. should be fairly accurate since thermal steady state is achieved. Results Comparison
