SPC singularities

Recommended Posts

I am creating an SPC acting on a single node ath the bottom left corner of my model to constrain translation in x, y and z direction and when i run analysis i get a stress concentration or singularity at this position.

 

My question is, what is the best way to avoid this high stress acting over a single node?

 

Here is an image of my results.

Hello tinh, thanks for the reply, at this moment i am a novice user at university.

 

I would imagine it would normally be supported by a bolt or a pin joint as rotation is not constrained but this has not been specified in the problem. Only that the structure is constrained in this corner and we are unable to modify the geometry.

 

Would it be advisable to spread the load over the edge nodes of this corner?
