Normal stress = F/a K = F/a/V/V = -FV/aV
If p represents the increase in pressure applied on the spherical body then F/a = p
k = -pV/V
Yes, the bulk modulus of elasticity increases with pressure. The bulk modulus measures the resistance of a material to changes in volume under applied pressure. As pressure increases, the material becomes less compressible and therefore the bulk modulus increases.
K(bulk modulus of elasticity)=-{[Pressure x volume]/change in volume}
1. Young's modulus of elasticity, E, also called elastic modulus in tension 2. Flexural modulus, usually the same as the elastic modulus for uniform isotropic materials 3. Shear modulus, also known as modulus of rigidity, G ; G = E/2/(1 + u) for isotropic materials, where u = poisson ratio 4. Dynamic modulus 5. Storage modulus 6. Bulk modulus The first three are most commonly used; the last three are for more specialized use
Pure de-aired water has a bulk modulus equal to approximately 2.2 GPa. There is a common misconception that fluids are totally incompressible, however as can be seen from the above this is not true (if it were, the bulk modulus would be infinitely high). It is reasonable to state that water is highly resistant to compression however. It should also be noted that the presence of dissolved gasses in water can significantly reduce this value so consider carefully the application or system being modelled before choosing an elastic modulus for water or any other fluid.
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.
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.
K(bulk modulus of elasticity)=-{[Pressure x volume]/change in volume}
there are different types of modulus it depends on what types of stress is acting on the material if its direct stress then then there is modulus of elasticity,if tis shear stress then its modulus of rigidity and when its volumetric stress it is bulk modulus and so on
When we talk about deformatation, we are referring to two properties, namely Elasticity and Plasticity. These properties are measured using constants known as " Moduli of Elasticity". There are 4 such moduli: Young's Modulus Axial Modulus Rigidity Modulus Bulk Modulus The larger the value of the Bulk Modulus, the harder it is to compress the material.

The expressions that are derived are from isothermal bulk modulus and its pressure derivatives. The pressure varies to create the ionic crystal.

The bulk modulus of a fluid is the measure of its compressibility. In SI units, the bulk modulus of sulfuric acid is 3.0 Newtons per square meter.
