In this analysis, an imposed displacement type resolution technique (“DDL_IMPO”) is used to find the solution. This method provides for each imposed displacement value, a load multiplier coefficient (“ETA_PILOTAGE”). The value of the load imposed in “AFFE_CHAR_MECA” is equal to the limit pressure, therefore the reference value of the parameter “ETA_PILOTAGE” is equal to 1.

The calculations were stopped when the value of parameter ETA_PILOTAGE stabilized.

The beam solution improves significantly when the mesh is refined.
