Push and pull auxiliary sweep

Please login with a confirmed email address before reporting spam


I try to model corrugated cardboard, to be precise I wish to model the creasing and scoring of corrugated cardboard. The creaser needs to be pushed and pulled back up to see plastic deformation on the board.

I use an auxiliary sweep, with a displacement as parameter, to crease to board, however the creaser has to be pulled back up again. How can I do that, such that the creaser and the board are not in contact with each other anymore? Is that plastic deformation shown immediately?

For the board I use a Orthotropic model, since the board experience different strenght properties in the three mutual directions. Under 'Linear Elastic Material' I added a plasticity model based on Hill orthotropic plasticity.

Thanks in advance!
