If you are exciting it at its natural frequency, you should be at a condition of resonance.
To see it in Abaqus, if I am understanding you correctly, make a new "Set". Maybe select the point of the load application as the set.
At the step where the periodic load is applied, make a new history...
Good evening all,
I have a little project going on here which requires the estimation of the wing loads on the lower wing skins of a large STOL aircraft.
The actual structure is not needed, I am just using an idealized structural representation using a given aircraft weight, planform, aspect...
The bottle is made of 4130 steel.
Because I do not know the actual thickness of the wall, I constructed a crude graph showing the internal tensile stresses developed within the wall of the vessel. (The whole wall thickness issue is another story in of itself)
During the hydrostatic test...
Good evening all,
I am looking at making a determination as to whether or not further NDI is useful once a hydrostatic test (completed every three years) is performed.
This NDI would consist of either a mag-particle or x-ray inspection.
Anyway, the regular operating pressure of the bottle...
