### Poisson s Ratio in Linear ViscoelasticityA Critical Review

Mar 01 2002 · Thus reliable information on theviscoelastic Poisson s ratio is as yet rather scanty. The paper also reports on attempts to measure the Poisson s ratioof a viscoelastic material as a function of temperature. Lateralcontraction in creep and at constant rate of extension receivesattention as well.

Chat Online### Summary of the Poisson s Ratio Debate CSEG

The Poisson s ratio is not a spectacular property it ranges from 0.05 to 0.20 for very strong materials and reaches a value of 0.5 for fluids with no shear strength. Compare this to seismic velocities ranging over an order of magnitude or even electrical or hydraulic conductivities covering many orders of magnitude.

An interesting observation during this study was the change in auxetic behavior (i.e. a change in Poisson s ratio with a change in the strain values). The film exhibited auxetic characteristics up to strain values of 1 . After this a transition from negative to positive Poisson s ratio (auxetic to nonauxetic behavior) was seen.

Jan 01 1983 · Printed in Great Britain 298 Kalman Schulgasser The Poisson ratio of paper is difficult to measure. The nature of the material is such that the probes used to measure cross-direction deformation when a sample in the form of a strip is loaded in tension can themselves influence this deformation. Hence optical methods seem appropriate.

Poisson s effect and the ratio of the contraction to the elongation is known as Poisson s ratio ν (nu). For "well behaved" materials 1 E and ν are all that is required to completely define the material s response to applied loads. The figure below illustrates the elastic modulus and Poisson s ratio.

Jul 15 2015 · ABSTRACT In the paper K. L. Ngai et al. J. Chem. 140 044511 (2014) the empirical correlation of ductility with the Poisson s ratio ν Poisson found in metallic glasses was theoretically explained by microscopic dynamic processes which link on the one hand ductility and on the other hand the Poisson s ratio.

Poisson s ratio had long been considered to be an intrinsic material property confined within a narrow domain and governed solely by the geometry of interatomic bonds. Materials with designed heterogeneity allow for control over the Poisson s ratio. Poisson s ratios of any value within the thermodynamically admissible domain may be attained including negative Poisson s ratio (termed auxetic

Chat Online### Poisson s ratio of plywood measured by tension test

Abstract In this research Poisson s ratio of plywood as obtained by a tension test was examined by varying the width of the specimen. The tension tests were conducted on five-plywood of lauan (Shorea sp.) with various widths and Young s moduli and Poisson s ratios of the specimens were measured. Finite element calculations were independently conducted.

The minor Poisson s ratio v 21 could either be measured in the same way with UD 90 degree specimens or it could be calculated according to Eq. as Choi and Lakes note (Choi and Lakes 1995) as with a piece of crumpled paper). The material hence has a negative Poisson s ratio. Figure 32.

Chat Online### Interpretation of experimental data for Poisson s ratio of

Abstract The Poisson s ratio of a material is strictly defined only for small strain linear elastic behavior. In practice engineering strains are often used to calculate Poisson s ratio in place of the mathematically correct true strains with only very small differences resulting in the case of many engineering amterials.

Jul 22 2017 · Poisson s ratio is a measure of the transverse strain relative to longitudinal strain Fung et al.1 Claimed that the Poisson s ratio is bounded between -1 and 0.5 for a linear elastic isotropic material. Cork is the material with zero Poisson s ratio. It was shown in the work of Ting2 that for anisotropic materials Poisson s ratio can be

Chat Online### Poisson s Ratio Definition and Formula of Poisson s Ratio

The Poisson s Ratio for most of the materials is in the range of 0 to 0.5. The Poisson s Ratio is between the range f 0 to 0.5 for plastics. When the Poisson s Ratio is 0 there is no reduction in the diameter or one can even say there is no laterally contraction happening when you are elongating the material but the density would reduce.
