Question

1. A solid cylinder of 6 inch diameter and 4 inch high is compressed aaioymmetrically to 2 inch high. Calculate the final diameter of the product, the three orthogonal strains and the von Mises strain: (5 points) a. Estimate the maximum total force required for this operation. Assume: coefficient of friction: 0.2; Use Ludwik's Law to find the pressure at maximum axial strain; the strength coefficient of the workpiece: K is 147 ksi, strain hardening exponent is 0.17. (5 points) b. 2. Draw the electrical circuit diagram of electromagnetic forming, label it neatly and explain hovw a thin cylinder can be expanded or compressed by this process. (S points) 3. Explain with a neat diagram the basic principle of Hydroform process (5 points) Use the other side of this page for more space to answer this question.
