Design and Applied Mechanics
The Applied Mechanics group pursues fundamental research on mechanics of solids, materials and structures. Members of this group develop and use modern analytical, computational, and experimental tools to engineer applications in materials (nanomaterials, Magnesium and other alloys, wood, paper and other composites), structures (marine and aerospace), and devices (Biomedical stents and catheters, bio-inspired adhesives). They attract funding from Natural Sciences and Engineering Research Council, Canadian Institutes of Health Research, Canada Foundation for Innovation, and industries from Canada and abroad.
The faculty members are Peter Cripton, Mohamed Gadala, Antony Hodgson, Thomas Oxland, Srikantha Phani, Mauricio Ponga, Gary Schajer, and Machiel Van der Loos. Some of the projects currently underway are outlined below.
Dr. Antony J. Hodgson — Medical Robotics, Biomechanics
Current Projects: Developing tools for computer-assisted orthopaedic surgery based on phase-processing of 3D ultrasound images to provide realtime 3D imaging information and on mini-robotic devices to enhance accuracy and shorten surgical time; designing a 3D scale model of the human eye to study sensorimotor issues; comparing surgical motor performance in simulators and the live operating room to validate simulators.
Dr. Peter Cripton — Biomechanics of Human Injury
Current Projects: Modeling spinal injuries to develop a helmet-mounted device preventing spinal injuries incurred in sports and transportation accidents, analyzing mechanisms of hip fracture to identify features predisposed to early fracture, and computational and experimental methods to evaluate performance of implantable spinal devices.
Dr. Mohamed Gadala — Finite Element Applications
Current Projects: Industry solution procedure for crack detection and propagation in rotating components, steel run-out table design, and electric fatigue of piezoelectric actuators.
Dr. Thomas Oxland — Orthopaedic Research
Current Projects: Revision hip replacement, fixation of the osteoporotic spine, regeneration of damaged neural tissue, behaviour of orthopaedic implants, and musculoskeletal tissues.
