    HYDRAULIC PRESSURE TESTING + AIR

    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...

    Element Size v Stresses

    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.

    VON MISSES STRESS

    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 ?

    PEDESTAL GUSSETS, SIZING

    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...

    VON MISSES STRESS

    THE VON MISSES STRESS IN A PLATE IS 12 KSI. FOR A36 STEEL IS MY SAFETY FACTOR 36/12 = 3 OR 58/12 = 4.8 IS VON MISS BASED ON YIELD OR ULTIMATE ?

    Z=0

    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...
