Axial pressure in Generalized Plane Strain

Axial pressure in Generalized Plane Strain

Axial pressure in Generalized Plane Strain

(OP)
Hello everyone,

I try to model in 2D a part under isostatic pressure which means I need to put a pressure in the direction 3 too.
However with Generalized plane strain elements it is only possible to put a concentrated load on the reference point.

Does someone know how i could enforce an axial pressure on the whole 2D surface ??

Thanks,

RE: Axial pressure in Generalized Plane Strain

Plane strain elements represent an infinite surface so applying a pressure in the 3 direction makes no sense. I believe the reference point is there to restrain the imaginary out of plane either in the 3 direction to have zero axial strain and/or the rotational directions. For generalised plane strain it's usual just to restrain the two rotational directions and leave the 3 direction free for thermal expansion, say.
