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.
