Attached in an image of a model I'm trying to accurately do a static simulation on (in Solidworks).
I have two slats in the horizontal plane and fourteen slats in the vertical plane - there is a cut out in each of the slats to allow them to overlap as shown. However, there is always a 0.5mm clearance gap between each of the slats. Consequently the only contact there is the model is between the weld beads – the weld beads joining the slats together, without the weld beads there is no contact. This is all as intended. I have applied the desired external loads and fixtures to my model, and it is now just a case of deciding on the correct method of 'contacts' to use - which is where I'm having problems. If I chose 'bonded' it will treat the contact areas as if I welded the slats together with infinitely-strong super glue. This show’s in my results as the weld show no sign of stress. My other option is to choose 'no penetration', then the simulation won't run - this is to be expected as there isn't any friction and my whole assembly would just fall to pieces. I don't want the contact to be infinitely strong, nor do I want it to be frictionless - I want it to accurately resemble how welds would behave under force. To do this the only idea way I can think of is to apply a coefficient of friction to 'no penetration' contact's (this as I can't see to get the 'Edge weld' connection to do what I want either; it too seems to treat my welds as infinitely strong-bonds). Has anyone else ever simulated the stress on a weld joint? If so am I going about it the right way? Thanks in advance, Tom.
