A composite bar with a 4” x 4” cross-section is modeled using SOLID185 elements. The bar consists of two different
materials with the material properties E1, E2, υ1, and υ2 as shown above. Twenty five MPC184 rigid beam elements
are then modeled running along the length of the bar. The rigid beam elements are given a coefficient of thermal
expansion, α3. The bar is fixed in all DOF’s at one end. As a temperature is applied to the model, the rigid beam
elements expand, in turn deforming the rest of the composite bar. As a result, two distinctly different stress levels ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–563 VM240
can be seen through the bar’s cross-section. These stresses reflect the material property differences of the two
materials making up the composite
