Active bending beam-shell element

Hi Karamba3D community,

I’ve been working in a transformable bending active module made of CFRP. I’ve had some trouble with the simulation stage because when I increase a point force at the end of element from -1.4 to -11 kN and it deforms, it tends to stretch and at the end this element is longer than the begining module.

I’ll let the file here, and I’ll appreciate any help. (53.3 KB)

Hi @Lmuribet,
this effect is due to the assumption of small displacements. Try to use the ‘Analyze Nonlinear WIP’- or ‘large Deformation analysis’-component instead.
