Microstructural characteristics and elastic modulus of porous solids

Microstructural characteristics of planar granular solids

The microstructure of granular materials is the main factor determining their macroscopic behaviour. We study systematically the statistical characteristics of volume elements (called quadrons) of microstructures of monoand polydisperse planar disc packs granular and report a number of new results. The packs analysed were of different intergranular friction coefficients ,μ , contained about 20,...

Modulus of elastic pdf

The modulus of elasticity Youngs modulus E is a material property, that. From the Hooks law the modulus of elasticity is defined as the ratio of the stress to.modulus of elasticity of the cultured SC cells examined in this study, in central, non-nuclear regions, ranged between. Johnson B.all require an effective E, the Youngs modulus or elastic modulus, to quantify. Elastic moduli, such as the ...

Elastic modulus of viral nanotubes.

We report an experimental and theoretical study of the radial elasticity of tobacco mosaic virus (TMV) nanotubes. An atomic force microscope tip is used to apply small radial indentations to deform TMV nanotubes. The initial elastic response of TMV nanotubes can be described by finite-element analysis in 5nm indentation depths and Hertz theory in 1.5nm indentation depths. The derived radial You...
