Kids studying to be ME told me they want to test a steel cylinder by filling it 90% to 95% with water and 10% to 5% with compressed air. The idea being that compressed air is readily available in their dad's garage, and that by filling only the 10% ~ 5% volume with air it is less dangerous. I...
As mentioned by crisb the transition meshing is critical. Our FEA engineer gave us the attached results. VMmax = 3.02 ksi for 1/4 and 1/10 mesh. 2.97 ksi for 1" mesh.
Ellas can you post your hand calcs. to compare.
EngAddict,
My boss thought the mesh was too coarse also. What would be the 'optimum' size of the elements for these plates. The designer said the elements are 3x3x3" on average. We will ask him to remesh the gussets and 1" base plate. Should we have the pipe remeshed smaller also ?
I am a 'Port Engineer' (run/maintenance of boats) not Structural. The design engineer gave us a structural detail on a small pipe pedestal welded to the deck. One of the gusset is showing a Principal stress of 14.027 ksi at the very tip of the gusset (screen print attached). The maximum...

We are stuck with 2D drawings that incude object on different planes (accidental 3D). When looked at in the XY plane they look good but some lines are really diagonals going from one object on one plane z=0 to another object on another plane z=1. I can correct this by selecting each object and...
