Ansys predefined materials are designed to capture the effect of a material’s chemical composition, powder-to-liquid and liquid-to-solid state transitions, and high cooling rates. Nonlinear thermo-physical properties such as thermal conductivity, density, and specific heat are essential for capturing solidification phenomena in metal additive manufacturing. The materials that have had complete validation tests performed and are recommended for Thermal Strain simulations are shown with a check-mark as Available for Thermal Simulation in the Materials Library and in the details panel for a material. Only those materials will be available for selection in the Material Configuration section of the Thermal Strain simulation form.
