Fatigue analysis
Thread Content
Since the equipment is under fatigue conditions, does the connection between the internal packing support beams and the housing also require fatigue analysis?
In my opinion, when performing fatigue analysis, it is sufficient to consider the shear load exerted by the packing support beam on the shell, in addition to the internal pressure
There is a sudden change in the load-bearing structure at the joint, requiring fatigue analysis; special attention must be paid to welded structures. There have already been many cases in China of cracks occurring at the welds between such non-pressure components and shells.
