WebAug 18, 2015 · Bulk Modulus When a body is subjected to three mutually perpendicular stresses, of equal intensity, then the ratio of the direct stress to the corresponding volumetric strain is known as bulk modulus. It is usually denoted by K. Mathematically, bulk modulus, K = Direct stress/Volumetric strain =σ / (δV/V) 1.
