Determine the force vs reduction in height curve in open-dye forging of a cylindrical, annealed copper specifmen 10mm high and 25mm in diameter, up to a reduction of 50% for the following cases:

a) no friction between the flat dies and the specimen

b) u=0.10

c) u=0.30

Ignore barreling and use average pressure formulas.

Then, calculate the work done and the temperature rise in the specimen for each case, assuming the process is adiabatic and and the temperature is uniform throughout the specimen.

Use the following values:

K=315KPa

n=0.54

Cp=380J/kgK

p(rho)= 8970k/m^3
