Performance of snow in confined compression

Journal of Terramechanics, 1977
Abstract The need to provide for input of mechanical properties of snow for prediction of vehicle mobility on snow requires determination of typical constitutive relationships for snow. The performance of various kinds of snow under confined compression is examined and evaluated in terms of initial snow structure.

Compression field modeling of confined concrete

Structural Engineering and Mechanics, 2001
The three-dimensional behavior of confined concrete was investigated, including strength enhancement due to triaxial compressive stresses, lateral expansion, compression softening, cover spalling and post-peak ductility. A finite element program based on a nonlinear elasticity methodology was employed to evaluate the ability to model triaxial behavior ...

Numerical method for vorticity confinement in compressible flow

AIAA Journal, 2002
It is well known that modern computational fluid dynamics codes based on Eulerian descriptions do not adequately handle flows involving the convection of thin vortical layers. These layers often remain very thin and persist long distances without significant dissipation. Over the past decade, Steinhoff has introduced a class of methods, generally known

Analysis of soil compression curves from uniaxial confined compression tests

Geoderma, 2011
Abstract The compressive behaviour of soil, the compression curve, is typically expressed in a semi-logarithmic diagram in the relationship between the logarithm of applied stress, σ , and the void ratio, e . The compression curve yields three important soil compression properties: the swelling index, C s , the compression index, C c , and the ...

Tissue-scale anisotropy and compressibility of tendon in semi-confined compression tests

Journal of Biomechanics, 2015
In this study, porcine tendon tissue was tested with a dedicated semi-confined compression set-up that enables us to induce states of either fibrils in compression (mode I), tension (mode II) or at constant length (mode III), respectively. The results suggest that tendon tissue is compressible and demonstrates a significantly stiffer response in mode I

Investigation of Vorticity Confinement in Compressible Flow

19th AIAA Computational Fluid Dynamics, 2009
To accurately capture vortical flow structures on relatively coarse grids, vorticity confinement might provide a cost-effective technique to counter the vorticity diffusing effect of numerical dissipation. Properties of the confinement term, added to the momentum equation, are studied analytically and numerically.

Compressibility of 4He Liquid Confined in Nuclepore

Journal of Low Temperature Physics, 1998
Adding and removing 4 He from an experimental cell which contains the porous material Nuclepore results in capillary condensation, hysteresis and avalanches. The volume of liquid in the nearly cylindrical pores is monitored with a capacitance technique.

Confined particle bed comminution under compressive loads

International Journal of Mineral Processing, 1996
Abstract Eight minerals and ores were comminuted batchwise in a piston-die press under defined conditions that eliminated geometrical effects of the particle bed. The influence of bed pressure, material hardness and feed size on energy absorption, energy utilization and product size distributions was investigated.

CFRP-CONFINED RUBBERISED CONCRETE UNDER MONOTONIC COMPRESSION

2023
This study aims to investigate the performance of rubberised concrete (RuC), confined with 2 layers of carbon fibre-reinforced polymer (CFRP). Cylindrical concrete specimens of a RuC mix and a conventional concrete mix were subjected to axial compression.

Compression resistance of confined timber stud walls

Proceedings of the Institution of Civil Engineers - Construction Materials, 2013
Hemp-lime is an insulating low carbon dioxide material that is produced from sustainable natural resources. The use of hemp-lime within the construction industry is a relatively recent development. Currently within the UK hemp-lime is used to form solid wall insulation in conjunction with structural timber studwork.
