& Mathematical Modelling of Materials & Processes
Welcome to the Solidification, Imaging & Mathematical Modelling of Materials & Processes (SIM3P) research laboratory of Dr. André Phillion in the Department of Materials Science & Engineering at McMaster University in Hamilton, Ontario, Canada.
Solidification Science & Application to Manufacturing
Our group is interested in mathematical modelling of materials and processes, and 3D materials science, with a special emphasis on casting, welding, and additive manufacturing technologies. The main focus of our research has been to model solidification across multiple length scales in order to investigate the relationships between heat transfer and fluid flow at the macro-scale with microstructure and defects. Our research has included 3D observation of solidification morphology and defects, assessment of constitutive properties, in-situ observation of intermetallic growth during solidification, and mathematical modelling to predict structure formation in an industrial context.
3D Imaging & Modelling of Materials & Processes
In the area of 3D imaging, our team's work is diverse. Our general focus is on addressing current technical industrial issues and future scientific challenges in the transportation, energy and natural resources sectors. Examples of research topics include investigating the strength and structure of cellulose-based products and composite materials, permeability in proton-exchange-membrane fuel cells, and degradation of lung tissue due to smoking. In each of these interdisciplinary topics, novel 3D characterization methods are combined with imaged-based mathematical modelling to derive new fundamental mechanistic insight. Recently, our research has focused on in-situ observation of metal additive manufacturing via X-ray radiography and diffraction techniques in order to better understand metal transport and solidification in this complex environment.
