The bulk modulus ( or ) 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 decrease of the volume. Other moduli describe the material's response (strain) to other kinds of stress: the shear modulus describes the response to shear stress, and Young's modu… Web18 rows · Jan 27, 2024 · Usually, bulk modulus is indicated by K or B in equations and tables.
