This is a useful resource I would suggest doing a google scholar search for LS-Dyna material for a sheet metal cut punch. What materials are y...

Here’s an overview of common constraints in LS-Dyna

I believe *constrained_extra_nodes_set would work for you. Basically, you create a node set of all nodes on the deformable part that you want to const...

You probably have read this already, but there's quite a bit that goes into Dyna calculations. Modeling a pipe as beams is a much more simplified appr...

How far off are your hand calculations from Dyna? You can try using and under-integrated shell formulation like 2 and see how that changes your result...

@nckylrd8 when you say "up" do you mean positive x? And are the rollers rotating correctly? Also is your friction defined correctly in your contact be...

Hi @minh_le, I'm assuming the erosion is for the battery cell? Have you tried removing the EM_control_erosion?

@javat33489 seems like a problem with the material / section / hourglass of the drill. Or you could have something weird going on with your mesh or a ...

Hi @mmia1, You can use Element Generation (EleGen) in the Mesh toolbar in LS-Prepost to extend a shell mesh from a mesh edge or curve.

Hi @jmart199, When you are making the changes, are you doing so within LS-PrePost and saving the model out that way? Try taking the original model ...

Hi @mmia1 Where are you measuring the stress from? And just to clarify, you have another simulation where you modeled the pipe with shell elements...

You are applying a pressure that doesn’t take into account material property or geometry of the part. Your resulting “pressure” from the fringe plot w...

@delron hm interesting…even still, curious what the end goal of doing something like this is

@delron Oh well that's your problem. Spotwelds are meant to connect nodes to surfaces, not beams. That's why you are getting the error. Wh...

You can also look at the residual force plots to find the trouble spots. I would assume there's a problem with the interface between the layers.
