ANSYS Mechanical 2019R3 includes the new capability to create Material Combinations.  A user can define a new combined material based on volume-weighted averages of individual materials.  Previously, a user would typically prepare a spreadsheet to perform this type of calculation.  A Material Combination can facilitate preparation of a simplified representative model for complex features like copper traces on a PCB layer for thermal analysis (for a higher fidelity approach to modeling traces, follow this link).

Material Combinations support most common properties for linear materials, including:

  • Thermal Conductivity
  • Density
  • Specific Heat
  • Young’s Modulus
  • Poisson’s Ratio
  • Coefficient of Thermal Expansion
  • Orthotropic Elasticity
  • Orthotropic Conductivity
