Dear Student,

When the deforming forces are such that there is a change in the volume of the body, then thestressproduced in the body is called volumestress. e.g. Solid sphere placed in a fluid under high pressure. Mathematically,Volumetric Stress= Load / Area = Pressure Intensity = dP.

the ratio of volumetric stress to the corresponding volumetricstrainin a body is always constant, which is called as Bulkmodulus of elasticity. It is denoted by the letter 'K'. Its S.I. Unit of stress is N m-2or Pa (pascal)
