Hydraulic stress is bulk modulus times strain

When an object undergoes hydraulic compression due to a stress exerted by a surrounding liquid, the pressure (hydraulic stress) on the object due to the fluid is proportional to the fractional change in the object’s volume due to that pressure and the bulk modulus of the object. Thus, bulk modulus of a substance is a measure of its resistance to bulk compression.
