Data |
Length = 6.0, Width = 0.2, Depth = 0.1
Young’s Modulus =10.0E6, Poisson’s ratio = 0.3
Coefficient of thermal expansion=1.265E-5, Reference temperature = 00F
Loading: Top surface is maintained at 2000F and bottom
surface is maintained at 1000F
Constraints: Fixed at one end.

Comments |
Deformation due to temperature loading is considered in this problem.
The aspect ratio of the elements of this problem is 5.0. Hence this
problem demonstrates the performance of various elements with such a high
aspect ratio. Both undeformed and deformed shapes are shown in the figure. |
