PLEASE HELP !!!Node displacement condition or Force applied uniformily

PLEASE HELP !!!Node displacement condition or Force applied uniformily

PLEASE HELP !!!Node displacement condition or Force applied uniformily

(OP)
Hello,
I am trying to apply an uniformly force into a surface (bowtie structure), however the nodes deform as if the force will deform in the middle (where no support is given by bowtie structure). Well, it make sense if I apply a pressure (which is the only parameter I find to apply as a force in a surface).

I would like the force to be applied to the entire surface though as if a steel plate will push a bowtie structure or a structure with support only in the corners basically). The deformation will not occur only in the middle but throughout the bowtie.

I am thinking on defining the nodes in the surface to have the same y-displacement. Is this possible? Or what could be another possibility?

Thank you very much

Yes, use an enforced Y displacement on the surface nodes.

How do I do that? I am pretty new at abaqus, sorry.

RE: PLEASE HELP !!!Node displacement condition or Force applied uniformily

Drigo, rather than ask basic questions here, you would be much better off by getting some training.

Taht will be nice...problem is how do I get trained (easy to say difficult to do). Is there any tutorial available, I thought this forum was for helping people.

RE: PLEASE HELP !!!Node displacement condition or Force applied uniformily

Drigo - you need to use *BOUNDARY on the nodes.  There is plenty of info on how to use it in the online docs that came with your ABAQUS install.
