Sum of principal stresses
WebThe well-known principle of the determination of the sum of principal stresses in plates by measuring thickness changes is applied in this paper to “frozen” plates and to models … WebThe equation to calculate Von Mises stress on a mechanical component. V = √ (σx2 – (σx * σy) + σy2 + (3 *txy2)) Where V is the Von Mises Stress. σx is the normal stress x component. σy is the normal Stress y component. τxy is the Shear Stress. When a mechanical component is acted upon by 3D loads a very complex three dimensional ...
