Last week, MASc candidate Hubert Villeneuve presented his thesis work, giving a talk titled “height estimation of a blimp unmanned aerial vehicle using inertial measurement unit and infrared camera”. The work was done under the supervision of Dr. Eric Lanteigne, who was also present for the talk. Well done, Hubert, congrats on presenting your work!
Kicking things off in 2017 was Simon Baril-Gosselin who presented his PhD thesis work on “Fabrication of carbon fibre opposites reinforced with carbon nanotubes”. Unfortunately, PhD supervisor Dr. François Robitaille was teaching and unable to attend. However, there was an enthusiastic audience and our grad students were kind enough to supply us with coffee and cookies (because all scientific talks are made better by coffee and cookies.
I collected the photos I took in 2016. Clearly, I should have taken more photos!
Last but not least for 2016, Aurelian Tanase presented his PhD thesis seminar, with PhD work completed under the supervision of Drs. Tavoularis and Groeneveld. The title of the talk was “flow and heat transfer in tubes with objects”.It was an interesting talk, followed by some delicious shawarma to round out our fall semester. Congrats Aurelian and here’s to 2017!
Last Friday, Catherine Kuforiji presented her PhD thesis work, giving a talk titled “Development of SS316L-AL2O3 composites for wear applications”. Supervisor Dr. Michel Nganbe was present for the seminar. Congratulations to student and supervisor for the (near) completion of this PhD work! Well done, Catherine, we are very proud of you.
After the talk, I had the honour of having my photo taken with Catherine too. 🙂
Last Friday, Erfan Niazi presented his PhD thesis seminar titles “Experimental and numerical investigation of red blood cells aggregation”. Supervisors Dr. Fenech and Dr. MacDonald were present (along with a few other interested professors!) well done, Erfan!
Rob Shaheen, under the supervision of Dr. Marc Doumit, presented his thesis seminar last Friday. The title of his talk was “Design and material characterization of a nonlinear, hyperelastic tubular soft composite”. Well done, Rob!
Yesterday, Nathan Kline presented his MASc work, under the supervision of Dr. Stavros Tavoularis. The title of the talk was “heat transfer to Co2 flowing in vertical tubes at supercritical pressures”. Well done, Nathan!
Last Friday, Hamid Fallah Haghmohammadi presented his thesis seminar on “fever detection for dynamic human environment”. Supervisor Dr. Dan Necsulescu was present in the audience. Congratulations for a successful thesis seminar presentation.
Last Friday featured a graduate seminar by my own MASc candidate,Bochun Zhang. Bochun gave a talk titled “Failure Mechanism Analysis and Life Prediction based on Atmospheric Plasma-Sprayed (APS) and Electron Beam-Physical Vapor Deposition (EB-PVD) Thermal Barrier Coatings”. Bochun’s primary supervisor was Dr. Kuiying Chen, from Canada’s National Research Council, and I was the cosupervisor. Unfortunately, Dr. Chen could not attend, but I’m sure he would have been as proud of Bochun as I was! Well done, Bochun.
The first seminar of the semester will be this Friday! MASc CandidateMajid Tanbakuei Kashani will be giving a talk on “Effect of Forming Process on the Deformational Behaviour of Steel Pipes”. The seminar abstract is below.
Date: Friday September 16th
Room: SITE J0106
Buried pipeline networks play a vital role in transportation of oil and natural gas from centers of productions to centers of consumptions. A common manufacturing technique for such pipes is the UOE process, where a flat plate is first formed into a U shape, then in an O shape, welded at the seam, and Expanded before being shipped on site. The UOE forming process induces residual strains in the pipe.
When buried pipelines cross the regions of discontinuous permafrost, they undergo differential frost heaving, inducing significant bending deformations, which potentially induce local buckling in the pipe wall. To control local buckling, design standards impose threshold limits on buckling strains. Such threshold values are primarily based on costly full-scale experimental results. Past nonlinear finite element analysis attempts aiming at determining the threshold buckling strains have neglected the presence of residual stresses induced by UOE forming and were thus found to grossly overestimate the buckling strains compared to those based experiments.
Within the above context, the present study focuses on developing a numeric technique to predict the residual stresses induced in UOE forming, and incorporating the residual stresses in 3D nonlinear FEA modeling to predict improved buckling strain limits. Comparisons against conventional analysis techniques that omit residual stresses reveal the importance of incorporating residual stresses when quantifying buckling strains.
