Hello
I use the different material model in simulation,turn the mat003 plastic kinematic to mat098 simplified johnson cook and increase the hardening value.the deformation decrease but it still unreasonable.its deformation like the wave swing. Is this due to the inertia of rotation?or mass scaling?how can I fix it?
Thanks
