Hi everyone,

I have never really used ANSYS before, but I have now have to design a blade that needs to cut through 20mm reinforced bar (the metal rods used in concrete beams). I was going to attempt to analyse it by hand but my supervisors said that it would be much too complex, and that ANSYS would be a much easier.

The movement of the blades act like a pair of scissors; with one blade stationary and the other rotating about a pivot.

I need to know the stresses and forces that the blade will experience when it cuts through the reinforced bar. Also a simulation that has a time step so that I know where and how large the forces are as the blades turn.

Photos of the cutting mechanism is in the following link:
