Thesis title
Multi-scale Simulation of Co-firing of Functionally Graded Materials
Research overview
Functionally Graded Materials (FGMs), with spatially varying properties, enhance performance in applications like solid oxide cells, gas separation membranes, capacitors, piezo actuators, and dental implants. Produced through powder metallurgy and sintering, FGMs face co-firing challenges such as shape distortion and cracking due to differential shrinkage rate in layers. Traditional optimization is inefficient and costly. This research aims to develop a multi-scale numerical model that integrates the continuum theory of sintering with the Discrete Element Method (DEM) to optimize distortion during the co-firing of FGMs by capturing realistic microstructural variables. This approach seeks to improve shape accuracy, optimize process parameters, and reduce optimization time and costs for FGM-based technologies.
