WebHydrostatic Stress As the hydrostatic stress is unlikely to influence deformation in a solid that deforms at constant volume, it may be surmised that it is the deviatoric components that will be the ones associated with the shape change. From: Mechanics of Sheet Metal Forming (Second Edition), 2002 Add to Mendeley About this page WebThe plastic behaviour of materials is often independent of a hydrostatic stress and this feature necessitates the study of the deviatoric stress. 8.2.1 Deviatoric Stress Any …
