When exploring poisson s ratio, it's essential to consider various aspects and implications. Understanding Poisson's Ratio and Restrained Cylinders. I have a couple of questions about Poisson's ratio I hope you guys can answer. If I have a cylinder made of, let's say steel. Steel has a Poisson's ratio of roughly 0.33. Building on this, the cylinder is restrained in the vertical direction so no displacement can occur.
If I apply an internal pressure... Equally important, why would density increase when Poisson's ratio > 0.5?. Homework Statement Does anyone understand why density would increase when the poisson ratio is greater than 0.5 as indicated in this slide from my professor: Does this density increase apply to a system undergoing tension or compression or both? Rate of change of volume and poisson's ratio - Physics Forums.
The discussion revolves around deriving the relative change in volume of a rectangular block of isotropic material subjected to axial deformation, specifically in relation to Poisson's ratio. Participants clarify that Poisson's ratio is indeed represented by the variable "v" in the equation G = E/ (2 (1+v)). The relationship between axial strain and transverse strain is emphasized, indicating ...
Water Poisson Ratio: What & How? Poisson's ratio can be calculated if you know the bulk modulus K and the shear modulus G of the material. In water, is one of these much greater than the other? Equally important, what does this imply about the Poisson's ratio?
From another angle, understanding Poisson's Ratio and Its Effects - Physics Forums. Hi everybody, Poisson's ratio determine that when applying force in one direction (let say z direction) it would cause a relative major strain at that direction, and also two additional strains at the two other directions (x & y). My question is, what is the explanation for the change in the...

Homework Statement Hollow Circular tube of Length (L) 600 mm is compressed by forces P (axially). Outside diameter (d2) is 75 mm. Modulus of Elasticity (E) is 73 GPa Poisson's ratio (v) is 0.33. Furthermore, axial strain (ε) is 781 x 10-6 Find shortening of tube (δ). Find Poisson's Ratio of Aluminum from Torsion and Tensile Tests.
Torsion test showed aluminum to have shear modulus of 4.60x10^6psi. Under a tensile test, the same specimen showed a modulus of elasticity of 12.2x10^6psi. Find Poisson's Ratio.
