To represent 1/8th of the structure, the imposed displacement boundary conditions are:
On nodes NO1, NO2, NO4, and NO3: \(DZ=0\).
On nodes NO3, NO4, NO8, and NO7: \(DY=0\).
On nodes NO2, NO6, NO8, and NO4: \(DX=0\).
The load consists of the same pressure distributed in compression over the 3 meshes: HAUT, DROITE and ARRIERE to simulate a hydrostatic test.
3.2. Tested sizes and results#
Component \(\varepsilon_{xx}\) at node NO6 was tested and compared to the reference solution:
