Many applications from geosciences require simulations of seismic waves in porous media. Biot's theory poroelasticity describes the coupling between solid and fluid phases introduces a stiff source term, thereby increasing computational cost motivating efficient methods utilising High-Performance Computing. We present novel realisation discontinuous Galerkin scheme with Arbitrary DERivative tim...

Murine models of osteoarthritis (OA) and post-traumatic OA have been widely used to study the development and progression of these diseases using genetically engineered mouse strains along with surgical or biochemical interventions. However, due to the small size and thickness of murine cartilage, the relationship between mechanical properties, molecular structure and cartilage composition has ...

Short-term changes in the hydraulic head of surface water bodies are known to influence the shallow response of hydraulically connected groundwaters. Associated with these fluctuations is the physical increase in stream water creating a mechanical load on the ground surface. This load is supported by the geologic materials (sediment or rock) and the pore fluid contained within the pores. Change...

An interesting and useful analogy can be drawn between the equations of static poroelasticity and the equations of thermoelasticity including entropy. The correspondence is of practical use in determining the effective parameters in an inhomogeneous poroelastic medium using known results from the literature on the effective thermal expansion coefficient and the effective heat capacity of a diso...

The two-scale computational homogenization method is proposed for modelling of locally periodic fluid-saturated media subjected a to large deformation induced by quasistatic loading. heterogeneities are relevant the mesoscopic scale at which double porous medium constituted hyperelastic skeleton and an incompressible viscous fluid featured contrasts in permeability. Within Eulerian framework re...

Fractured porous media or double porosity are common in nature. At the same time, accurate modeling remains a significant challenge due to bi-modal pore size distribution, anisotropy, multi-field coupling, and various flow patterns. This study aims formulate comprehensive coupled continuum framework that could adequately consider these critical characteristics. In our framework, fluid micro-fra...

Two views have dominated recent discussions of the physical basis of cell shape change during migration and division of animal cells: the cytoplasm can be modeled as a viscoelastic continuum, and the forces that change its shape are generated only by actin polymerization and actomyosin contractility in the cell cortex. Here, we question both views: we suggest that the cytoplasm is better descri...

Compared to typical asphalt mixtures, poroelastic mixtures are characterised by high porosity and flexibility, which desirable for traffic noise reduction. However, the same properties increase risk of debonding from lower layer, is a significant source premature damage. The study investigates factors – tack coat agent, type texture layer have greatest impact on interlayer bonding quality. From...
