The bulk modulus (which is usually positive) can be formally defined by the equation K = − V d P d V , {\displaystyle K=-V{\frac {dP}{dV}},} where P {\displaystyle P} is pressure, V {\displaystyle V} is the initial volume of the substance, and d P / d V {\displaystyle dP/dV} denotes the derivative of pressure with … See more The bulk modulus ($${\displaystyle K}$$ or $${\displaystyle B}$$) of a substance is a measure of the resistance of a substance to compression. It is defined as the ratio of the infinitesimal pressure increase to the resulting relative … See more It is possible to measure the bulk modulus using powder diffraction under applied pressure. It is a property of a fluid which shows its ability to change its volume under its pressure. See more • Elasticity tensor See more Strictly speaking, the bulk modulus is a thermodynamic quantity, and in order to specify a bulk modulus it is necessary to specify how the pressure varies during compression: constant-temperature (isothermal $${\displaystyle K_{T}}$$), constant- See more Interatomic potential and linear elasticity Since linear elasticity is a direct result of interatomic interaction, it is related to the extension/compression of bonds. It can then be derived from the interatomic potential for crystalline materials. First, let us examine the … See more WebApr 3, 2024 · The bulk modulus is a measure of the energy can be stored in the liquid. This coefficient is analogous to the coefficient of spring. The reason that liquid has different coefficient is because it is three dimensional verse one dimension that appear in regular spring. The bulk modulus is defined as.
