Bulk modulus - Wikipedia

The bulk modulus (or ) of a substance is a measure of how resistant to compression that substance is.It is defined as the ratio of the infinitesimal pressure increase to the resulting relative decrease of the volume. Other moduli describe the material''s response to other kinds of stress: the shear modulus describes the response to shear stress, and Young''s modulus describes the response to

Equivalent bulk modulus - HAWE Hydraulik

The equivalent bulk modulus is not a constant magnitude, but instead a function of the pressure. This situation applies above all for the low pressure range. The reason for this relationship is the mostly unavoidable undissolved air content of the oil as well as the non-linear expansion of hoses (Figure E 35). Figure E 35: Equivalent bulk
