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 omitted, 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 definition.

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 ABAQUS Analysis User’s Manual) to
be used to specify the second-order accurate element formulation option, a nondefault hourglass
control formulation option, or scale factors.

In an ABAQUS/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
