K=E/(3*(1-2v))
K: Bulk modulus
E: young modulus
v: poison's ratio
on the other hand:
delta V/V=(1-2v)*delta L/L
relative change in Volume equals to: (1-2v) * relative change in length.

If a material has a young's modulus of 220GPa and a poisson's ratio of 0.29 what is its bulk modulus?
The bulk modulus (K) is a material's resistance to uniform compression from all directions. If you have Young's Modulus (E) and Poisson's ratio (ν), the relationship is: K = E/(3*(1-2ν)) For E = 220 GPa and ν = 0.29, K = 174.603 GPa
What is the difference between modulus of compression and bulk modulus and some special for compression?
Modulus of Compression is the ratio of stress to strain in an uniaxial compression action, while as, bulk modulus is the ratio of volumetric stress (hydrostatic pressure) to volumetric strain in hydrostatic loading. These two modulii are inter-related though and are written with the use of Poisson's ratio. 1/m = (3K-E)/6K 1/m = Poisson ratio K = Bulk Modulus E = Elastic Modulus Satisfied? - tell others, not satisfied? - tell me.
Can bulk modulus be used to find the stress-strain relationship of a material compressed in a single axis?
Yes, if the material is very thin in ther axis of compression. If it is not thin, as in compressing a long cyclinder, you do not need to know bulk modulus. If very thin it won't make a lot of difference if it a metal with usual poisson ratio of about 0.25, but will make difference for possion ratio higher, especially approaching 0.5, as in rubber. In the case of the long cyclinder stress = modulus xstrain In the case of the thin material stress = modulus x strain times the quantity (1-u)/ ((1+u)(1-2u)) where u = poisson ratio; the relation to bulk modulus for u is u =1/2 - E/6B where B = bulk modulus and E = elastic modulus

What is the poissons ratio value for M30 concrete?

Prove that poissons' ratio is 0.5?
since k=E/3(1-2n): where k=bulk modulus and n=poision's ratio it can be seen that value of poision's ratio can't be smaller than 0.5 in order to keep k be +ve.hence poision's ratio is 0.5
What is the ratio between stress and strain called?
Young's modulus
What is the material poisson ratio of Epdm?
Depends on the hardness of the formulation. Poisson's ratio depends mainly on the bulk modulus and slightly on the Youngs modulus at very low strains for the subject compound. If the Youngs modulus lies between 0.92 and 9.40MN/m², Poisson's ratio lies between 0.49930 and 0.49993.

Relation between youngs modulus and modulus of rigidity and poisson's ratio?
G = E/2(1+u) where G = mod of rigidity and u =poisson ration and E = young modulus
What is the linked between modulus of elasticity and modulus of rigidity?
It is around 40 GPa.
What will be the poison ratio and youngs modulus for S275JR EN10025?
Young's modulus-205 kN/mm2 Poisson's ratio = 0.30
Modulus of rigidity is the ratio of?
It is the ratio of shear stress to shear strain.
What is Young's modulus and poisons ratio of a liquid?
Liquids are not defined by elastic modulus, but rather by bulk modulus, which for water is about 2200 MPa (320,000 psi). It is nearly incompressible, with a Poisson ratio close to, but not quite,0.5
