Stabilized mixed finite elements for deformable porous media with double porosity
Coupled problem Double porosity Effective stress Mixture theory Stabilized finite elements Twofold saddle point problem
2015/7/1
Natural geomaterials such as fissured rocks and aggregated soils often exhibit a pore size distribution with two dominant pore scales, usually termed macropores and micropores. High-fidelity descripti...
On the effective stress in unsaturated porous continua with double porosity
Constitutive behavior Geological material Granular material Microstructures Porous material
2015/7/1
Using mixture theory we formulate the balance laws for unsaturated porous media composed of a double-porosity solid matrix infiltrated by liquid and gas. In this context, the term ‘double porosity’ pe...

Porosity长椅 Steven Holl
2009/9/10
Porosity长椅是由美国著名建筑师Steven Holl于今年设计。该设计采用竹子作为原料，每块竹板都经过数位切割后相互锁在一起，从而拼接成一把完整的座椅。另外，在每块竹板上都切割出不规则的长孔，当阳光穿透长孔时，会在地面及座椅本身留下不规则的光影效果。该座椅为限量发售，共10把，其基本尺寸为：W162×D62×H97cm。
