Required parameter:
ELSET
Set this parameter equal to the name of the element set containing the shell elements for which the
section behavior is being defined.
Required parameter in ABAQUS/Explicit, optional parameter in ABAQUS/Standard:
DENSITY
Set this parameter equal to the mass per unit surface area of the shell.
If the MATERIAL and COMPOSITE parameters are om itted, this density accounts for the
mass of the shell, since no material definition is given.
If the MATERIAL or COMPOSITE parameter is used, the mass of the shell includes a
contribution from this parameter in addition to any contribution from the material defini tion.
Optional parameters:
CONTROLS
In an ABAQUS/Explicit analysis, set this param eter equal to the nam e 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 second-order accurate element form ulation option, a nondefault hourglass
control formulation option, or scale factors.
In an ABAQU S/Standard analysis, set this parameter equal to the name of a section
controls definition to be used to specify the enhanced hourglass control formulation (see “Section
