SOLID SECTION
Required parameter for anisotropic materials optional parameter for isotropic materials:
ORIENTATION
Set this parameter equal to the name given for the
*
ORIENTATION option (“Orientations,”
Section 2.2.5 of the ABAQUS Analysis User’s Manual) to be used to define a local coordinate
system for material calculations in the elements in this set. This param eter is required when the
material is anisotropic.
For a c omposite solid this orientation, together with the orientation angle specified on the layer
data lines, can also be used to define the material orientations in the individual layers. Alternatively,
a materialorientationcan bespecified byreferencing anorientationdefinitionon eachlayer dataline.
In this case the reference given on the ORIENTATION parameter is ignored. Any layer definition
line that does not have an orientation reference or an angle specified will use the section orientation
defined on the keyword line.
Optional parameters:
CONTROLS
In an ABAQUS/Explicit analysis, set this parameter equal to the name of a section controls
definition (see “Section controls,” Section 21.1.4 of the AB AQU S Analysis User’s Manual) to be
used to specify a nondefault hourglass control fo rmulation option or sca le factor. The
*
SECTION
CONTROLS option can be used to select the hourglass control and order of accuracy of the
formulation for two- and three-dimensional solid elem ents and to select the kinematic formulation
for 8-node brick elements.
In an ABAQUS/Standard analysis, set this parameter equal to the name of a section controls
definition (see “Section controls,” Section 21.1.4 of the ABAQUS Analysis User’s Manual) to
be used to specify the enhanced hourglass control formulation or to be used in a subsequent
ABAQUS/Explicit import analysis.
STACK DIRECTION
This parameter applies only to ABAQUS/Standard analyses.
This parameter can be used only with composite elements. It defines the stacking direction
with respect to a pair of element faces. Set this param eter equal to 1, 2, or 3. The default is STACK
DIRECTION=3.
ORDER
This parameter can be used only with acoustic infinite elements in ABAQUS/Explicit. It defines
the number of ninth-order polynomials that will be used to resolve the variation of the acoustic field
in the infinite direction. Set this parameter equal to N to indica te that the first N members of the set
of ninth-order polynomials are to be used. The default is ORDER=10, which is the value always
used in ABAQUS/Standard.
