Notes:
For a given sheet metal forming process, an accurate determination of the contactpressure distribution experienced is an essential step towards the estimation of tool life. Thisinvestigation utilizes finite element (FE) analysis to determine the evolution and distribution ofcontact pressure over the die radius, throughout the duration of a channel forming process. It wasfound that a typical two-peak steady-state contact pressure response exists for the majority of theprocess. However, this was preceded by a transient response, which produced extremely large andlocalized contact pressures. Notably, it was found that the peak transient contact pressure was morethan double the steady-state peak. These contact pressure results may have a significant influenceon the tool wear response and therefore impact current wear testing and prediction techniques.Hence, an investigation into the validity of the predicted contact pressure was conducted
