Loading T1 = 0 °F T2 = 100 °F Analysis Assumptions and Modeling Notes 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 The equations below are used to calculate theoretical...
