The compaction model used here is one developed by Gavi and Reynolds (2014), and is also included in the FormulatedProducts module of the gPROMS software package (henceforth called gFormulate), produced by Process Systems Enterprise (PSE, 2018). The model has several key equations. The first ...
(1). However, a chart of empirical equations for Gmax presented in [45] shows that the value of α ranges between 0.4 and 0.6 depending on the void ratio e. In the small-medium strain regime, the shear modulus is not constant over the magnitude of strain. The shear stress shows a ...

Scientists and engineers encounter considerable environmental and economic obstacles stemming from the depletion of crude oil or petroleum fossil fuel reservoirs. To mitigate this challenge, alternative solutions like bio-oil-modified binder derived from
of buried explosion with varying degree of confinement. Factors affecting crater formation and ground shock propagation in media are discussed in detail. An overview of various prediction methods developed over the years based on dimensional analysis and theory of similarity to estimate crater dimensions...
emplacement compaction contributed to regional mud volcanism24. However, we identified possible mud volcanoes partly covering regional polygonal trough sections (e.g., Fig.S3e), indicating a formation that must have long postdated the megatsunami's emplacement and its early tectonic modifications (Fig...
Given that the current ballasted tracks in Australia may not be able to support faster and significantly heavier freight trains as planned for the future,
We perform the analysis of the available empirical compaction equations for fine-fraction materials. By modeling separate stages of the process of compaction for selected groups of materials, we reveal the advantages and drawbacks restricting the fields of their possible applicati...
If the wall temperature rather than heat flux is known, then following set of equations can be used to calculate the hTP: (I.25)q2=(FhLΔTS)2+(ApSΔTS)2q4/3 (I.26)Ap=55pr0.12(−log10pr)−0.55M−0.5 (I.27)qL=FhLΔTS (I.28)q*3=[qFhLΔTS]3=[qqL]3 (I.29)C=(...
Binders, which are additives designed to increase strength after compaction, may reduce or increase friction, depending on the chemistry and conditions. 5.2.2 Sintering and Microstructure Development Sintering Overview. Parts made by compacting powder at room temperature are porous. To decrease the ...
