contact_area of Three-Roll Passes #238

Closed RichardPfr closed 3 weeks ago

RichardPfr commented 1 month ago

The current contact_area calculation on the Roll is used for Two- and Three-Roll Passes and takes the in- and out-Profile widths as an input. For Three-Roll Passes this should be to large of an estimation though, as seen here: newplot

This is also especially the Case when this is then multiplied by 3 for the entire rollpass.

We should therefor handle the calculation for Three-Roll Passes differently.

Might be better to handle the contact area for ThreeRollPasses based on a 120° section and not the entire Profile:
