Unlike other forms of stress that can involve twisting or shearing, hydrostatic stress involves only a pure compression or a pure tension. 8-mm-thick low-carbon steel sheet is experimentally investigated. This includes what is traditionally referred to in the literature as the The hydrostatic stress referred to in the following sections is the stress at the centre of the interconnect. C'est une forme de contrainte qui s'applique également dans toutes les directions In simpler terms, hydrostatic stress is a state of stress where the material is subjected to equal stresses in all directions, resulting in a change in volume but not shape.
