  • Water Poisson Ratio: What How? - Physics Forums
    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? What does this imply about the Poisson's ratio?
  • Rate of change of volume and poissons ratio - Physics Forums
    and Poisson's ratio The block of material is subjected to axial deformation along the c dimension 1 Derive an expression for the relative change in volume, change in V V , in term of Poisson's ratio 2 Make a plot of the relative change in volume, change inV
  • Poissons ratio, steel rod for example - Physics Forums
    Steel has a "Poisson ratio" μ of 0 29 (in my book of problems at least) Am I understanding the meaning of this ratio correctly: if a steel cylinder is stretched along its symmetry axis by a factor p (something like 1 01 or 0 99) then the radius will change by a factor 1-μ(p-1)? [So then the
  • Why would density increase when Poissons ratio gt; 0. 5? - Physics Forums
    Alright so here calculated what the volume change would be for when Poisson's ratio < 0 5 It told me that the volume would decrease which implies that the density increases But according to the lecture notes this is not true Instead when the ratio is < 0 5
  • Understanding Poissons 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
  • Understanding Poissons Ratio and Restrained Cylinders - Physics Forums
    Hey 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 The cylinder is restrained in the vertical direction so no displacement can occur If I apply an internal pressure
  • Poisson ratios for Orthotropic materials (composites) - Physics Forums
    In the FEM software I use I need to specify three Poisson ratios: ##\nu_{12},\ \nu_{23},\ \nu_{31}## (and also three E and three G moduli) It is orthotropic material (3 symmetry planes) I want to derive the other Poisson ratio's because I want to know if the supplier provided a consistent set of data
  • Calculate Poissons ratio of NaCl crystal - Physics Forums
    hello to all here is a problem i designed myself i don't know whether it can be solved Question: Consider NaCl lattice of edge length 'x' m Let Na+ carry +1 C and each Cl- carry -1 charge Calculate Poisson's ratio of NaCl crystal Assume no heat loss when deformation takes place
