Finite element analysis of the effect of porosity on residual stress in 2024 aluminium alloy GTAW
Materials Research Express, 2020 Simulations of the welding process for butt joints using finite element analysis (FEA) of the effect of porosity are presented. The metal used was aluminium alloy (grade 2024), and the filler material was alloy ER5356.

Journal of Ocean Engineering and Science, 2023 In the present article, we have used the three-phase-lag model of thermoelasticity to formulate a two dimensional problem of non homogeneous, isotropic, double porous media with a gravitational field impact. Thermal shock of constant intensity is applied

Acta Physica Sinica, 2014 A new algorithm for P-wave reverse time migration (RTM) in a fracture-induced TTI double-porosity medium is proposed in this paper, by combining RTM with the method of P-and S-wave field separation in high-order staggered grid finitedifference scheme.

Homogenized modeling for vascularized poroelastic materials [PDF]
, 2017 A new mathematical model for the macroscopic behavior of a material composed of a poroelastic solid embedding a Newtonian fluid network phase (also referred to as vascularized poroelastic material), with fluid transport between them, is derived via ...

Differentiability, porosity and doubling in metric measure spaces [PDF]
Proceedings of the American Mathematical Society, 2012 We show if a metric measure space admits a differentiable structure then porous sets have measure zero and hence the measure is pointwise doubling. We then give a construction to show if we only require an approximate differentiable structure the measure need no longer be pointwise doubling.

Natural convection and the evolution of a reactive porous medium [PDF]
, 2011 We describe a mathematical model of buoyancy-driven flow and solute transport in a saturated porous medium, the porosity and permeability of which evolve through precipitation and dissolution as a mineral is lost or gained from the pore fluid. Imposing a

Generalized theory of thermoelastic diffusion with double porosity
Archives of Mechanics, 2018 The present paper focuses on the derivation of the constitutive relations and field equations for anisotropic thermoelastic medium with mass diffusion and double porosity. The variational principle, uniqueness and reciprocity theorems are also derived.

Development of covalent triazine frameworks as heterogeneous catalytic supports [PDF]
, 2019 Covalent triazine frameworks (CTFs) are established as an emerging class of porous organic polymers with remarkable features such as large surface area and permanent porosity, high thermal and chemical stability, and convenient functionalization that ...
