The expression for wires drawing stress
Explanation of Solution
Formula used:
The expression flow stress is given as,
Here,
Calculation:
The figure (1) shows the force analysis during the extrusion process,
Figure (1)
Here,
Evaluate the forces in the x-direction,
Ignoring the second order terms in the above equation and divide whole equation by
Since positive pressure is indicated by negative stress,
From equation (1),
By equation (2) and (3),
On further solving,
Boundary conditions are as follows,
At
Integrating both sides in the limits,
