Simulation Express Exaggerating Deformation

  Posted by Siemens Community , 07 December 2017 · 11 views

Hoping someone out there understands Simulation Express better than me!

 

I simply want to check basic sheet metal parts for deformation relative to a certain level of pressure drop across (differential) a panel. The test below is done with .18 GA steel with the material table shown and a 0.0721824 PSI (2" wc) pressure applied. Very low force per unit of area. The simulation runs and shows massive deformation. For fun, i tried setting the load to force and applied 1 lb. The same result. What am I dong wrong?
