Iman Sedighi
Iman is currently a PhD student at the University of Alberta, with experience on experimental characterization of materials, and a focus on fracture mechanics. Joining Dr. Hogan’s group since September 2023, his research project involves analyzing the fatigue crack growth in welded steel pipes. The objective of his research is to study these phenomena experimentally and numerically in different length scales.
Jie Zheng, PDF
Dr. Jie Zheng is currently a postdoctoral fellow at CDAM, and graduated with a PhD degree at the University of Alberta under the supervision of Jamie. His PhD research mainly focuses on investigating fracture and fragmentation behaviours of advanced ceramics (e.g., boron carbide and alumina) under dynamic loading by using both the meso-scale and micro-scale methods. One of his goals is to estimate the fragment size and crack speed using advanced numerical methods. Being a PDF, Jie will shift his focus on the additive manufacturing of SiC-based ceramics and ceramic composites on aerospace applications, focusing on the manufacturing, characterization, and applied testing of printed coupons and parts. He will also use his expertise in computational modelling for combined CFD-FEM-based multi-physics process simulations.
Junhao Chang
Junhao is a PhD candidate under the supervision of Dr. Hogan at the University of Alberta. His research mainly concentrates on phase transformation (e.g., amorphization) of advanced ceramics (e.g., boron carbide) under dynamic loadings (i.e., shock). One of his current research goals is to build a comprehensive molecular dynamics unit cell model for the prediction of the fracture of boron carbide. After that, he will extend his model to study the dynamic behavior of advanced ceramics under complex loading conditions and damage states, and bridge into higher scale models that are studied in the group.
Kasra (Mohammad) Rezasefat, PDF
Kasra (Mohammad) Rezasefat obtained his PhD in mechanical engineering from Politecnico di Milano, where he studied the behavior of hybrid composites under extreme loadings. His primary research interests revolve around computational mechanics, multi-scale modeling, additive manufacturing, extreme loading conditions, and mechanical and materials design. He first joined the CDAM as a visiting scholar at the end of 2021.He is currently working as a postdoctoral researcher, investigating the stress-state- and strain-rate dependent behavior of additively manufactured ceramics. His work is expected to guide design of weight-optimized high-performance additively manufactured ceramic-based structures for use in vital Canadian industries.
Saman Sayahlatifi
Saman is a PhD candidate at the University of Alberta. Saman's PhD research project is dedicated to metal matrix composite (MMC) coatings, in which he wants to address the behavior of MMC coatings – Al-Alumina coatings, for instance – under different mechanical loading such as fatigue and wear through computational approaches. Indeed, he is focused on 3D microstructure-based FE simulation of MMC coatings subjected to loadings in field to provide an experimentally-validated FE framework to explore the effect of microstructure of these heterogeneous materials on their macro-scale behavior. Subsequently, this validated computational framework can result in an appropriate dataset for employing other predictive procedures with a much higher speed like machine learning (ML) or neural networks as a subset of ML methods.
Sara Sheikhi
Sara is a PhD candidate at the University of Alberta with expertise in Computational Solid Mechanics, Theoretical Methods, and Advanced Materials. The focus of her PhD thesis is to develop new interatomic potential for Boron Carbide using Machine Learning and Molecular Dynamics approaches, and bridge it into higher-scale models developed by other group members through implementing homogenization schemes.
Weihao Guo
Weihao is a current PhD student at the University of Alberta, with experience on the cutting force and thermal modeling and testing during the root canal preparation. His PhD thesis focuses on the morphological characterization, mechanical testing, and physics-based finite element modelling of skull bone. The objective of his research is to inform on the fundamental material behavior of human skull bone and helmet design under various loading conditions.
Zahra Zaiemyekeh
Zahra is currently pursuing her PhD under the supervision of Dr. Hogan in the CDAM Lab. The main focus of her PhD research is on mechanical behavior and failure of ceramics under a wide range of strain rates and stress states. Mechanical testing data obtained through experimental procedures in combination with employing Ultra-high-speed imaging and Digital Image Correlation (DIC) is essential for providing insights into the mechanical behavior of ceramics across a variety of conditions and also transitional behavior between intact, damaged, and fragmented states. Moreover, these experimental verifications can lead to the development of robust models.
