Home / Examples / Stress Analysis [Galileo] / Example 17: Material with Anisotropic Coefficient of Thermal Expansion

The analysis model has the anisotropic coefficient of linear thermal expansion.
The deformation under thermal load is solved.
The deformation, the displacement distribution, and the stress distribution are solved.
Unless specified in the list below, the default conditions will be applied.
Results will vary depending on Femtet version and the PC environment.
