Nettet15. apr. 2005 · Poisson's ratio of the polymer–glass composites as function of glass content. The Ep / Em ratio of the system is 41. The upper and lower bounds proposed in the present study are also compared with other theoretical models. The most popular theoretical model to estimate the elastic modulus is the Hashin–Shtrikman (H–S) model … http://resource.npl.co.uk/docs/science_technology/materials/measurement_techniques/uncert/cop16.pdf

Limits to Poisson

Nettet(m 12 = -strain direction 2/strain in direction 1) Typical values for Poisson's ratio range from 0.0 to 0.5. For a fibrous composite the following equation can be used: m 12 = V f * m f + V m * m m where the properties are measured in the 12 plane. Poisson's ratio for local plane 12 can be referred to as the major Poisson's ratio. NettetThe value of Poisson's ratio is the negative of the ratio of transverse strain to axial strain. For small values of these changes, is the amount of transversal elongation divided by … diy smart mirror from monitor
