Advanced Mathematical Models for Casting
Abstract:
Existing simulation tools for modeling of casting cannot predict
the segregation and cast-in residual stresses or do so only crudely
despite the strong effect of these phenomena on the final quality
of the cast parts. In addition, the existing tools for mold filling
and solidification are numerically inefficient and do not
incorporate other physical effects (e.g., shrinkage and latent heat
release) in an accurate or integral way. We propose to develop an
advanced modeling tool that handles filling, solidification,
segregation, and stress evolution using an advanced, efficient
numerical algorithm. The resulting software will model the full
casting process and yield detailed compositional and stress fields
throughout the cast part. In Phase I, we will demonstrate efficient
calculations for each of these fields. We will develop a full
integrated software package and validate it in Phase II.
The resulting modeling tools will represent a major advance over
those currently available and will have an excellent commercial
market for use in a wide range of industrial casting settings, both
through displacing less capable software and by significantly
broadening the market by the addition of new capabilities and much
greater computational efficiency.
