v3.01.012 SSLL12 - Bar lattice under three stresses

Summary:

Static response in linear mechanics of the structures of a triangulated system of articulated bars (plane truss) under 3 stresses:

• support displacement,

• point forces,

• dilation effect.

This test makes it possible to validate element BARRE under various load cases. It also validates option LIAISON_OBLIQUE of the AFFE_CHAR_MECA command.
