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.
