I work with sheet metal weldment. The problem that I am having is getting the stress gradient to transfer between parts. First I tried welds between the parts and then I tried bonding between the parts. And nothing seemed to work.

are you using solids or shells or a combination of both
have you tried setting up a really simple model (that you can post) to see if it is your model or your method.
overall, you should just be able to bond using contact sets to connect them in the load path.
The weldment is predominatly shell elements.
I have tried the bonding techniques on a simple model and they work great.
One thing that I have noticed that is different from the simple model to the working model weldment is the fact that in the simple model the node points of the mating elements matched up with each other. In the working model the mesh was individual to each part and the nodes did not match up. even with bonded surfaces.
mightb e worth some screenshots of your model and how you're defining contact.
The right picture is the weldment screen shot.
probably best to just upload a pack and go zip of your model and the parts.
if it were me, i'd exclude all the components except for 2 and focus on that connection until it works. to really troubleshoot the problem, someone is going to have to see what the itnerface bnetween those copmonents looks like and also how you define the contact in the software.
The original model is quite large for a pack-and-go. What is your association with Solidworks? Do you work for Dassault Systems?
Sorry for being forward but I have to know where my model will be going.
Hi Dylan, I work for Hawk Ridge Systems which is a reseller on the west coast of the US and across Canada.
Which file do I pack - and - go to get the FEA model.
What is your email address? I do not know how to send this zip file through this interface.
you can use the advanced editor at the top to post the model to the forum
but you can send it to me directly using my dropbox at http://dropbox.yousendit.com/jaredconway.
I have tried to post the file to the forum but was unsucessful. Your dropbox was unclear as to how to attach the files to the dropbox.
In any case, I was not sucessful in send you the zip file.
hi dylan, email me at firstname.lastname@example.org for some more instructions.
