Spring 2018
This thesis explores the effect of fluid substitution, pore-pressure diffusion and stresses due to hydraulic fracturing on the elastic velocities and microcrack orientations in the surrounding rock. I develop a workflow incorporating three main components to model the velocity field around the...

With a growing elderly population, osteoporotic pelvic fractures have been an increasingly common worldwide problem. Due to the complexity of the human pelvis, difficulties exist in the diagnosis of subtle fractures and complications may arise from standard treatments. Guidelines for approaching...

Lo, Calvin, Sano, Tomoko, Hogan, James D.
We investigated the uniaxial compressive behavior of damaged and intact alumina using quantitative X-ray computed tomography (XCT) analysis coupled with digital image correlation (DIC) for mechanical characterization. Internal three-dimensional crack characteristics such as crack surface area and...

An ever increasing demand to exploit oil and natural gas reserves has significantly increased extraction activities even in the remotest regions of the Arctic and sub-Arctic regions of the Canadian North. Steel pipelines are the most efficient mode for transporting and distributing these...

Impact Failure of Planetary Materials: Lateral Field Ejecta Measurements using Particle Image Velocimetry
Download2014
Schneider, Markus, Spray, John, Rogers, Robert, Hogan, James, Vincent, Gregory
The dynamic fragmentation of a fine grained granitoid material has been examined. Target thicknesses ranged from 7 to 40 mm and impact energies from 12 to 2,500 J. Combined particle image velocimetry and image enhancement techniques are introduced and have been used to measure the size and...

In-situ visualisation of dynamic fracture and fragmentation of an L-type ordinary chondrite by combined synchrotron X-ray radiography and microtomography
Download2021-05-01
Farbaniec, Lukasz, Chapman, David J., Patten, Jack R.W., Smith, Liam C., Hogan, James D., Rack, Alexander, Eakins, Daniel
The relationship between the dynamic mechanical properties of stony meteorites and their microstructures was investigated in-situ for an L-type ordinary chondrite using a split-Hopkinson pressure bar apparatus and ultra-high speed phase-contrast X-ray radiography at the European Synchrotron...

The pelvic bone is one of most stressed bones in the human body due to its essential task of weight-bearing of upper body. However, pelvic bone fractures usually occur as a result of high-rate impact loads, high cycle with low magnitude (e.g., stress fractures) or bone diseases such as pelvic...

On the evaluation of mechanical properties and ballistic performance of two variants of boron carbide
Download2021-06-01
Lo, Calvin, Li, Haoyang, Toussaint, Geneviève, Hogan, James D.
A comparative study on the microstructure, rate-dependent compressive behavior, and ballistic performance of commercially available pressureless sintered boron carbide-titanium diboride (material Z) and hot-pressed boron carbide (material S) was conducted. Under quasi-static compression at rates...

The Effects of Microstructure and Confinement on the Compressive Fragmentation of an Advanced Ceramic
Download2014
Farbaniec, Lukasz, Shaeffer, Matt, Ramesh, K.T., Hogan, James
We investigate the rate-dependent compressive failure and fragmentation of a hot-pressed boron carbide, under both uniaxial and confined biaxial compression, using quantitative fragment analysis coupled with quantitative microstructural analysis. Two distinct fragmentation regimes are observed,...

Fall 2023
Surrogate headforms are employed in injury biomechanics to reconstruct head impact scenarios and evaluate protective equipment. The development of human calvarium surrogates to mimic mechanical response at fracture would be an essential step forward in improving the biomechanical biofidelity of...
