Then, define a single static, general step named Compress
mount
. When hyperelastic materials are used in a model,
Abaqus
assumes that the model may undergo large deformations; but large deformations
and other nonlinear geometric effects are not included by default in
Abaqus/Standard.
Therefore, you must include them in this simulation by toggling on
Nlgeom; otherwise,
Abaqus/Standard
will terminate the analysis with an input error. Set the time period to
1.0
and the initial time increment to
0.01
(i.e., 1% of the total step time).
For the purpose of restricting output, create a geometry set named
Out
at the vertex located at the lower-left
corner of the steel plate region.
Write the preselected variables and nominal strains as field output to the
output database file every increment. In addition, write the displacements at a
single point on the bottom of the steel plate to the output database file as
history data so that the stiffness of the mount can be calculated. Use the
geometry set Out
for this purpose.
