Hi,
I am modeling a soda can, and just for the heck of it I am doing a stress analsys. I have the material made of aluminum, and the dimensions and everything are accurate. I am putting x amount of force to the top of it, and a fixed constraint to the bottom. No matter if the force is .00001 psi or 1,000,000 psi, the can ALWAYS deforms (compresses, and always to the same amount). This is unrealistic, as .00001 would do nothing and a million would make it look like a pancake. Am I doing something wrong, or is this just the way it is?
Also, when do I use force and when do I use stress? And when do I use fixed/frictionless constraints?
Thanks!
