Hi @javat33489, I believe your implementation is fine as long as your units are correct. But I'd like to question whether removing elements is the ...
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...
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
