Abstract:

X-ray tomographic imaging provides a unique view of the internal structure of materials in 3D. Materials such as paper and proton transport layers (PTLs) are traditionally difficult to characterize because they are very thin and thus sustain only a limited amount of load. In this talk, new image analysis methods to quantify porosity in thin sheet material, and to segmenting paper fibres are presented. Then, the processed datasets are used as the basis for characterizing the strength, permeability, and diffusivity of these complex material systems via image-based simulations.

Biography:
Dr. Phillion received his PhD from the Department of Materials Engineering at The University of British Columbia in 2007, where he combined high temperature experimental methods with multi-
scale modelling to investigate solidification processes and casting defects. After completing his PhD, he spent two years (2008-2009) as a Post-doctoral fellow at EPFL, Switzerland in the LSMX Computational Materials, followed by six years (2010-2015) as a faculty member in the School of Engineering at The University of British Columbia’s Okanagan campus. He joined McMaster University in 2016.
