### 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 materials response to other kinds of stress: the shear modulus describes the response to shear, and Youngs modulus describes the response to linear stress.

Bulk modulus equation Questions: 1) What is the bulk modulus of a body that experienced a change of pressure of 5*10 4 N/m 2 and a its volume goes from 4 cm 3 to 3.9 cm 3?.. Answer: The bulk modulus is calculated using the formula, B = ΔP /(ΔV/V) B = (5*10 4 N/m 2)/((4 cm 3 - 3.9 cm 3)/4 cm 3) = 0.125 *10 4 N/m 2.

Bulk modulus is more strongly sensitive to water saturation. The bulk volume deformation produced by a passing seismic wave results in a pore volume change, and causes a pressure increase of pore fluid (water). This has the effect of stiffening the rock and increasing the bulk modulus.
