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 [...]
In this article we will discuss about how to analyze strain in metal forming process. Deformation: If on the application of forces, the particles of a deformable body change their relative positions with respect to one another, the body is said to be deformed. However, if there is no change in the relative positions of the particles with respect to [...]
In this article we will discuss about how to analyze stress in metal forming processes. Stress State at a Point: Let us first examine what comprises a complete state of stress at a point. State of stress at a point comprises the stress vectors or components of stress vectors acting on three mutually perpendicular planes passing through the point. With [...]
