Poisson's ratio

n
(General Physics) a measure of the elastic properties of a material expressed as the ratio of the fractional contraction in breadth to the fractional increase in length when the material is stretched. Symbol: μ or ν

The most influencing factor is surface wave speed which is based on soil e-modulus, density and poisson ratio.
In current study effects of backside coating parameters including, elastic modulus, thickness, specific mass and Poisson ratio are investigated in AM-AFM.
Rock physical interpretation revealed that Poisson Ratio is inversely proportional to the Bulk, Shear and Youngs modulai attributing to wetness ofthe rock by means offormation fluids.
For the thermoplastic polymers, the plastic Poisson ratio is usually ranged from 0.
ij] is the tensor of mechanical strains, u is the vector of mechanical displacements, f is the vector of the external volumetric forces, E is the temperature-dependent modulus of elasticity of the material, v is the temperature-dependent Poisson ratio of the material, [[delta].
A cross section shown in Figure 5 is the intercepted plane of a rectangular rigid strip foundation of width 2b and depth b embedded in a homogeneous half plane with shear modulus G, Poisson ratio v, and artificial damping ratio [zeta].
Numerical properties of intra-aneurysmal pressure impact fluid velocity membrane displacement and the deformed radius with respect to the Poisson ratio membrane thickness and extensional rigidity are studied.
The objective of this research was to determine the effect of dry bean at irrigation systems (non-irrigation, drip irrigation) on physical properties (length, width, thickness, sphericity, surface area, volume, bulk density, true density and porosity) and mechanical properties (angle of internal friction, static coefficient of friction, Poisson ratio and pressure ratio).
That is why the value of the Poisson ratio is practically constant and its minimum occurs for 30[degrees] (or 210[degrees]).
