Hydrostatic compression on polypropylene foam [PDF]

open access: yes, 2008
Models currently used to simulate the impact behaviour of polymeric foam at high strain rates use data from mechanical tests. Uniaxial compression is the most common mechanical test used, but the results from this test alone are insufficient to ...

Fracture prediction approach for oil-bearing reservoirs based on AVAZ attributes in an orthorhombic medium

open access: yesPetroleum Science, 2018
Fracture systems in nature are complicated. Normally vertical fractures develop in an isotropic background. However, the presence of horizontal fine layering or horizontal fractures in reservoirs makes the vertical fractures develop in a VTI (a ...

Parametric Study on the Sensitivity of Different Properties of Waves Propagating through an Incompressible Medium

open access: yesMathematics, 2023
This article deals with the study of disturbance that travels through the transversely isotropic medium in the form of waves. The particles of the considered medium have an additional property of small-scale internal rotation along with macroscopic ...

Logging while drilling electromagnetic wave responses in inclined bedding formation

open access: yesPetroleum Exploration and Development, 2019
For real-time inversion and fast reconstruction of formation true resistivity, the forward modeling of electromagnetic wave logging while drilling is usually based on the transversely isotropic formation model with vertical symmetry axis (VTI medium ...

STRESSED STATE OF A SYSTEM OF THREE PARALLEL TUNNELS WITHOUT DRAWING FROM OWN WEIGHT OF AN ANOTROPHONE ROCK MASSIF

open access: yesВестник Дагестанского государственного технического университета: Технические науки, 2019
Objectives. The aim of the study is to carry out a parametric analysis of the stress state of an anisotropic rock massif on the contours of the workings of a system of three parallel circular tunnels without lining due to the mass of the massif, for ...

Surface wave characteristics in a micropolar transversely isotropic halfspace underlying an inviscid liquid layer [PDF]

open access: yes, 2014
The present investigation deals with the propagation of waves in a micropolar transversely isotropic half space with an overlying inviscid fluid layer. Effects of fluid loading and anisotropy on the phase velocity, attenuation coefficient, specific loss ...

Impact of local thermal non-equilibrium on temporal thermo-hydro-mechanical processes in low permeable porous media [PDF]

open access: yesE3S Web of Conferences, 2020
The thermo-hydraulic-mechanical (THM) response of low permeable media is of crucial significance in thermal fracturing for production of unconventional shale oil, enhanced geothermal systems, and waste disposal.
