| Abstract: | This
study is related to reverse engineering solution of friction and yield stress
in a hot ring compression test using finite element method (FEM). Ring material
is steel and test temperature is 800°C. Load deflection curve and the deformed
geometry, obtained from the test, are considered as the benchmark parameters
for the reverse engineering. The numerical experimentation has been carried out
in an iterative manner. The values of friction are varied to find the final
geometry matching with the actual deformed shape. Having established the
friction, yields stress is varied to match the tonnage employed in the test. It
is observed that FEM can be very helpful in such kind of reverse engineering
problems. |
