Permeability of Fractured Media under Confining Pressure: A Simplified Model
An elastic-plastic model was developed to describe the deformation and permeability of fractured rocks under confining pressure. Elastic and elastic-plastic contact models were used in the model to analyze the deformations of a representative element containing a single fracture under various confining pressures. The present work utilized elements from contact mechanics and viscous flows to der...
متن کاملA multifunctional magnetic material under pressure.
Fe(II)(Metz)6](Fe(III)Br4)2 (Metz = 1-methyltetrazole) is one of the rare systems combining spin-crossover and long-range magnetic ordering. A joint neutron and X-ray diffraction and magnetometry study allows determining its collinear antiferromagnetic structure, and shows an increase of the Néel temperature from 2.4 K at ambient pressure, to 3.9 K at 0.95 GPa. Applied pressure also enables a f...
متن کاملDetermination of the hyperelastic material properties of the intervertebral disk under dynamic compressive loads
In the last decade, many finite element (FE) models of the spine were used as surrogate experiments to provide relevant knowledge on the biomechanics of spinal trauma [1-2]. One of the major concerns in the development of such model is the modeling and validation of the spinal components’ mechanical behavior in dynamic loading conditions. For instance, very few FE models have considered the str...
متن کاملFractal design for efficient brittle plates under gentle pressure loading.
We consider a plate made from an isotropic but brittle elastic material, which is used to span a rigid aperture, across which a small pressure difference is applied. The problem we address is to find the structure which uses the least amount of material without breaking. Under a simple set of physical approximations and for a certain region of the pressure-brittleness parameter space, we find t...
متن کاملMaterial Properties of Brittle Bones
INTRODUCTION Osteogenesis imperfecta (OI) is a genetic disorder of type I collagen that results in bone fragility. This fragility is believed to stem from a combination of bone mass deficiency and compromised bone material properties [13]. Little data, however, is yet available to describe bone material properties in individuals with OI. This study presents the first characterization of bone ma...
