WebHere the hydrostatic type of stress is known as "spherical stress tensor" and the other is known as the "deviatorial stress tensor". It will be seen later that the deviatorial part produces changes in shape of the body and finally causes failure. The spherical part is rather harmless, produces only uniform volume
