    Abstract: A method, device and article of manufacture for determining properties in a high pressure die cast component. Upon receipt of geometric information that corresponds to a location of interest within the component, a ray-triangle intersection relationship is used to calculate a wall thickness of the location of interest; this relationship is simplified by being used in conjunction with an octree-based relationship. One or more calculations are performed to determine a skin thickness based on the calculated wall thickness, and the skin thickness calculations are based on at least one of a logarithmic relationship, a polynomial relationship and a power law relationship. Changes in component shape or size may be taken into consideration to adjust the remaining skin layer thickness, such as that when the as-cast component is exposed to subsequent machining or related post-casting operations. From this, the properties are mapped to allow node-by-node variations in mechanical properties based on whether the node resides in the component skin region or core region.

    Abstract: A device and article of manufacture to predict material properties of a cast aluminum-based component. In one form, a computer-based system includes numerous computation modules programmably cooperative with one another such that upon receipt of data that corresponds to the cast aluminum-based component, the modules provide performance indicia of the material. The modules include a thermodynamic calculation module, a thermal-physical property module, a mechanical property module and a materials selection or alloy design module. The combination of the modules along with known material and geometric databases—in addition to microstructural and defect databases—promotes the generation of materials properties needed for casting design, casting process simulation, CAE nodal property mapping and durability analysis.
