Formation and growth of multiple, distinct ice lenses in frost heave

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 47, Issue 1, Page 82-105, January 2023., 2023
Abstract This paper presents a fully coupled thermo‐hydro‐mechanical (THM) model which simulates frost heave in fully saturated soils. The model is able to simulate the formation and growth of multiple distinct ice lenses. The basic equations of the system were derived using the continuum theory of mixtures, nonequilibrium thermodynamics, and fracture ...

Ionization Potential Depression and Fermi Barrier in Warm Dense Matter: A First‐Principles Approach

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Ionization potential depression (IPD) is of crucial importance to understand and accurately predict the properties of dense, partially ionized plasmas. Many models of IPD have been developed that, however, exhibit largely varying results. Recently, a novel approach was proposed that is based on first‐principles quantum Monte Carlo simulations ...

Failing by design; exploring the currere lived experiences of a low‐socioeconomic status boy in primary school

open access: yesThe Curriculum Journal, EarlyView.
Abstract This phenomenological research draws upon Pinar's concept of currere to frame the lived experiences of Cian, a young boy in an economically disadvantaged primary school in Ireland. By adapting Pinar's 4‐stages of currere research (regressive, progressive, analytic and synthetic), we explore Cian's personal and academic lived experiences over a

Hypergolic droplet‒film interaction dynamics at high temperatures

open access: yesDroplet, EarlyView.
The whole reaction process can be distinctly identified as three stages based on the corona size and the temperature temporal evolution. In the coalescence regime, T* maintains quasi‐stationary values during initial contact, corresponding to hydrodynamic coalescence process. Consequently, the first stage is defined as the inertia‐dominant stage. In the

A review of multiscale numerical modeling of rock mechanics and rock engineering

open access: yesDeep Underground Science and Engineering, EarlyView.
Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...
