Uniaxial compression of 3D printed samples with voids: laboratory measurements compared with predictions from Effective Medium Theory
Filip P. Adamus, Ashley Stanton-Yonge, Thomas M. Mitchell +2
3D printing technology offers the possibility of producing synthetic samples with accurately defined microstructures. As indicated by effective medium theory (EMT), the shapes, ori…
Multi-porous extension of anisotropic poroelasticity: linkage with micromechanics
Filip P. Adamus, David Healy, Philip G. Meredith +1
We attempt to formalise the relationship between the poroelasticity theory and the effective medium theory of micromechanics. The assumptions of these two approaches vary, but both…
Multi-porous extension of anisotropic poroelasticity: consolidation and related coefficients
Filip P. Adamus, David Healy, Philip G. Meredith +2
We propose the generalisation of the anisotropic poroelasticity theory. At a large scale, a medium is viewed as quasi-static, which is the original assumption of Biot. At a smaller…
A high pressure, high temperature gas medium apparatus to measure acoustic velocities during deformation of rock
Christopher Harbord, Nicolas Brantut, Emmanuel David +1
A new set-up to measure acoustic wave velocities through deforming rock samples at high pressures (up to 1000 MPa), temperatures (up to 700C) and differential stress (up to…
