Summary of results
======================

The results obtained using the various sub-integrated elements stabilized by the "assumed strain" method are very close to the results provided by the incompressible quadratic elements, as can be seen on the graph below. This graph brings together the results for various elements:

    "HEXA8 ", "elements HEXA8classiques"
    "QUAD4 ", "elements QUAD4classiques"
    "HEXA20 ", "elements HEXA20quadratiques"
    "HEXS20 ", "incompressible HEXA20quadratiques elements"
    "HEXS8 ", "integrated HEXA8sous elements"
    "QUAD8 ", "elements QUAD8quadratiques"
    "QUAS8 ", "incompressible QUAD8quadratiques elements"
    "QUAS4 ", "integrated QUAD4sous elements"


We thus note the good quality of the solution given by the under-integrated elements and the disappearance of the stress oscillations given by the linear classical elements.

In addition, the HHO models give excellent results, without any lock down.
