Determining Stress in Metal Forming Process | Metallurgy
For determining the normal and shear stresses on an inclined plane is by a graphical construction popularly known as Mohr's stress circle or simply Mohr's circle. For the sake of simplicity we take the co-ordinate axes along the principal stresses as shown in Fig. 3.5. The equations of the previous section when referred to this co-ordinate system become as given [...]
