Abstract Seismic numerical modelling involved in each stage of seismic exploration process is aimed at predicting seismograms an assumed subsurface medium. The energies and phases waves vary with the presence fluids, while frequency-dependent reflections a reservoir hydrocarbons was explained using diffusive-viscous wave (DVW) equation. We proposed Galerkin finite-element method (FEM) to numeri...

During the downslope long-distance movement of debris avalanches, particles interact with each other in various modes, by rolling, sliding and colliding other. transport, grains may undergo breakage, changing size shape. However, research on avalanches at grain scale remains limited, particular, evolution morphology different scales, from overall form down to surface roughness, runout distance....

In this paper, we examine the coupled thermoporomechanical behaviour of a fluid-saturated porous medium of infinite extent bounded internally by a fluid-filled cavity. The mechanical behaviour of the porous skeleton can either be Hookean elastic or elasto-plastic, with a constitutive response corresponding to a modified Cam Clay plasticity model. The fluid within the cavity can be subjected sim...
