Based on ductility exhaustion theory and the generalized energy-based damage parameter, a new viscosity-based life prediction model is introduced to account for the mean strain/stress effects in the low cycle fatigue regime. The loading waveform parameters and cyclic hardening effects are also...

A particle finite element method (PFEM) based model is proposed to analyze droplet dynamics problems, particularly droplet spreading on solid substrates (wetting). The model uses an updated Lagrangian framework to formulate the governing equations of the liquid. Curvature of the liquid surface is...

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...

Hydrothermal processing, a thermochemical approach, is an excellent method of converting energy-rich biomass into useful products. This approach offers the advantage of handling biomass with relatively high moisture content by precluding an energy-intensive pretreatment step. Hydrothermal...

Verma, Aman, Nimana, Balwinder S., Olateju, Babatunde, Rahman, Md. Mustafizur, Radpour, Saeidreza, Canter, Christina E., Subramanyam, Veena, Paramashivan, Deepak, Vaezi, Mahdi, Kumar, Amit

The growth in bitumen and synthetic crude oil (SCO) production in the Canadian oil sands industry has superseded pipeline capacity growth in recent years, leading to the increased interest in the transport of crude oil by rail to desired markets. However, the specific techno-economic parameters...

Hydrogen production via steam methane reforming (SMR) dominates the supply to refining complexes worldwide, resulting in significant greenhouse gas (GHG) emissions. There is a considerable demand for clean hydrogen pathways that are economically competitive with SMR. The development of a 563 MW...

The availability and low cost of natural gas in North America open the possibility of transporting it to places where there is significant demand. Natural gas can be transported long distances as liquefied natural gas (LNG). In this paper, data-intensive techno-economic models were developed to...

There is a high demand for natural gas in the Asia-Pacific region. Most of this gas is exported from the Middle East, Australia, Indonesia, and Malaysia. There is interest in the Asia-Pacific to diversify its import portfolio. From a Canadian perspective, there are abundant resources of natural...

China relies heavily on coal for power generation, and the demand for coal in a country of this size makes China the world’s largest carbon dioxide emitter; hence China is pursuing greener pathways for power generation. Importing shale gas in the form of LNG from Canada is one such pathway. It...
