Plastic Deformation and the temperature rise
Plastic Deformation and the temperature rise
(OP)
Can anyone suggest about "How to find temperature rise during severe plastic deformation of a metal" say during torsion or any other deformation process ?





RE: Plastic Deformation and the temperature rise
q = σεpV
Also if it is adiabatic
q = mcpΔT
If all the energy input is dissipate as heat
ΔT=σεp/(ρcp)
If you have a less simple case, the idea is the same but it takes a little more work. Of course, as always watch the units.
