Hi all,
I am currently studying the displacement of a sheetmetal plate at my work.
For this specific case I have a certain load applied in specific spots, and I need to know to max displacement because I have a limit i cannot pass, in my case 0.9 mm.
When I run a simulation with this plate I have created I got a result of 0.93 mm which is not good enough, so I add a sheetmetal bar on the bottom of the plate, that in reality will be assembled together using rivets.
The problem is when I run the simulation with the bar, I get the same max displacement with almost the same distribution, and this assuming that the whole contact surface of the bar and the plate are bonded.
I cannot find any mistake in the way I have setup the simulation and assembly (i have discussed this with fellow colleagues at work, but this cannot be true, it just doesn´t make sense that adding a bar is not increasing the stiffness of the whole assembling.
Can anyone give some tips or advice on how to to constrain and set up 2 parts together?
