| ABSTRACT: |
Accurate prediction of the evolution of sintering bodies is essential to many manufacturing processes. Many models and constitutive relationships have been developed. However, such models are very idealized and are not able to capture the evolution of real structures at the local and global levels simultaneously. Methods for the macroscopic and mesoscopic simulation of the behavior of materials during the sintering process are presented. The primary macroscopic method discussed is the application of constitutive equations in the finite element method of analysis. For mesoscopic models, the focus is on Monte Carlo statistical simulations of sintering. After looking at the weaknesses of each of these approaches, the coupling of the two is analyzed for it's feasibility and effectiveness in providing a more realistic simulation of sintering that can be used to not only predict macroscopic shrinkage or mesoscopic grain growth, but also model the local properties that occur in particular parts of a specimen. Problems with implementing this idea are discussed along with potential solutions, and thus focus in on the objectives of the proposal. |
