Stiffness of polymer chains
A formula is derived for stiffness of a polymer chain in terms of the distribution function of end-to-end vectors. This relationship is applied to calculate the stiffness of Gaussian chains (neutral and carrying electric charges at the ends), chains modeled as self-avoiding random walks, as well as semi-flexible (worm-like and Dirac) chains. The effects of persistence length and Bjerrum’s lengt...
متن کاملStiffness of compression devices
The static stiffness index (SSI) is mathematical equation that results in a simple number when the sub-bandage pressure in the supine position is subtracted from the subbandage pressure in the standing weight-bearing position. When SSI data are reported, often a wide range of values is observed for similar materials. The aim of this study was to explore the strength and weakness of the SSI and ...
متن کاملThe Dependence between the Strength and Stiffness of Cortical Bone Is Similar Fortension and Compression
INTRODUCTION A strong positive correlation between the apparent ultimate strength and stiffness of bone tissue has been observed for cortical bone in tension and low-density cancellous bone in compression [1]. For practical purposes, the existence of a relationship between strength and stiffness is significant in that bone strength can be predicted using non-invasive stiffness measurements. Fro...
متن کاملImprovement of Strength Parameters of Sand Reinforced with Polymeric Fibers
Triaxial consolidated drained, unconfined compression, and CBR tests have been conducted in order to study the stress-strain, strength, and volume change characteristics of fine sand specimens reinforced by polymeric fibers made from carpet wastes. The variables are aspect ratio (length/width) and weight percentage of the fibers. The results indicate that the peak strength and total volume chan...
متن کاملstiffness and deformation characteristics of a cemented gravely sand
the deformation and stiffness characteristics of a cemented gravely sand was investigated using triaxial equipment. the triaxial tests were conducted in both dry and saturated undrained conditions. artificially cemented samples are prepared using gypsum plaster as the cementing agent. the plaster was mixed with the base soil at the weight percentages of 1.5, 3, 4.5 and 6. the applied confining ...
