The bulk modulus is a constant the describes how resistant a substance is to compression. As we know the formula for Bulk Modulus, K =. Stainless steel with Bulk Modulus 163 109 Pa is approximate 80 times harder to compress than water with Bulk Modulus 2.15 109 Pa.

It may be calculated using the formula: Bulk Modulus ( K ) = Volumetric stress / Volumetric strain Bulk Modulus of Elasticity is the ratio of stress to change in volume of a material subjected to axial loading. If a material obeys Hooke's Law it is elastic. Biyernes, Abril 01, 2011. The bulk modulus of a material may be measured by powder diffraction, using x-rays, neutrons, or electrons targeting a powdered or microcrystalline sample. Strength of Materials Formulas ... E=proportionality constant called the elastic modulus or modulus of elasticity or Young’s modulus, P a. Piosson's Ratio. The bulk modulus of the material of the object is 120000 MPa. It is denoted with a symbol of K. It has the dimension of force per unit area.

Change in pressure, δP = 0.0 – 0.1.

V × Δ P Δ V. \frac { V \times \Delta P} {\Delta V} ΔV V ×ΔP. It is defined as the ratio between pressure increase and the resulting decrease in a material's volume. The constant, E, is the modulus of elasticity, Young's modulus or the tensile modulus and is the material's stiffness.

Young's modulus is in terms of 10 6 psi or 10 3 kg/mm 2. Solution: As given values in the problem: Bulk modulus, K = 120000 MPa. Other elastic modules include Young’s modulus and Shear modulus. Strength of Materials Formulas. In any case, the bulk elastic properties of a material is used to determine how much it will compress under a given amount of external pressure. The modulus is insensitive to a material's temper. Bulk Modulus is related to Modulus … Bulk modulus of elasticity is one of the measures of mechanical properties of solids.

It is expressed in the units of in the English system and N/m 2 in the metric system. Normal force is directly dependent upon the elastic modulus.

Strength of Materials Mechanics of Deformable Bodies. \Delta P = -0.1 MPa. Bulk modulus is termed as the proportion of volumetric stress related to the volumetric strain of a specified material, while the material deformation is within elastic limit. Together with Young's modulus, the shear modulus, and Hooke's law, the bulk modulus describes a material's response to stress or strain.
