3D Microstructure-Based Finite Element Simulation of ColdSprayed Al-Al2O3 Composite Coatings Under Quasi-Static Compression and Indentation Loading
Download2021-07-27
Sayahlatifi, Saman, Shao, Chenwei, McDonald, André, Hogan, James D.
This study developed microstructure-based finite element (FE) models to investigate the behavior of cold-sprayed aluminum–alumina (Al-Al2O3) metal matrix composite (MMC) coatings subject to indentation and quasi-static compression loading. Based on microstructural features (i.e., particle weight...

A Compressible Fluid Flow Model Coupling Channel and Porous Media Flows and Its Application to Fuel Cell Materials
Download2020-01-01
Jarauta, A., Zingan, V., Minev, P., Secanell, M.
A multi-dimensional, compressible fluid flow solver, valid in both channel and porous media, is derived by volume-averaging the Navier-Stokes equations. By selecting an appropriate average density/velocity pair, a continuous, stable solution is obtained for both pressure and velocity. The...

Stickle, Angela, Hogan, James, Kimberley, Jamie, Ramesh, K.T.
Modeling of catastrophic disruption requires understanding the processes of dynamic failure and fragmentation. This paper summarizes current mechanisms and models for dynamic failure, strength, and fragmentation, reviewing these from a mechanics perspective and with an emphasis on making links to...

A comparative study between optimal metal and composite rotors for flywheel energy storage systems
Download2018-11-01
Most recent research on flywheel rotors has focused on high-speed composite rotors as the storage element of the flywheel energy storage system (FESS). Literature research indicates that this is primarily due to the high specific energy of composites compared to metals. However, a quantitative...

A finite element-convolutional neural network model (FE-CNN) for stress field analysis around arbitrary inclusions
Download2023-11-01
Rezasefat, Mohammad, Hogan, James D.
This study presents a data-driven finite element-machine learning surrogate model for predicting the end-to-end full-field stress distribution and stress concentration around an arbitrary-shaped inclusion. This is important because the model’s capacity to handle large datasets, consider...

Rahman, Md., Mustafizur, Khan, Md., Mohib-Ul-Haque, Ullah, Mohammad, Ahsan, Zhang, Xiaolei, Kumar, Amit
Canada has many isolated communities that are not connected to the electrical grid. Most of these communities meet their electricity demand through stand-alone diesel generators. Diesel generators have economic and environmental concerns that can be minimized by using hybrid renewable energy...

A life cycle assessment of OME (oxymethylene ether) synthesis from biomass-derived syngas as a diesel additive
Download2017-01-01
Mahbub, Nafisa, Oyedun, Adetoyese Olajire, Kumar, Amit, Oestreich, Dorian, Arnold, Ulrich, Sauer, Jörg
The life cycle energy consumption and greenhouse gas (GHG) emission performances of forest biomass-derived oxymethylene ether (OME) synthesis used as a diesel additive are analyzed in this study. OME, a new alternative liquid fuel, has great miscibility with conventional fuels like diesel. OME...

Sperling, F. A. H., Polet, D. T., Flynn, M.R.
Microstructures on insect wings can promote directional drop shedding, and the local orientation of these structures is expected to facilitate drop removal. However, microstructures may exhibit very different orientations at different locations on the wing. Using the march fly Penthetria...
