Parameters
----------
name
A String specifying the repository key.
layup
A SectionLayerArray object specifying the shell cross-section.
symmetric
A Boolean specifying whether or not the layup should be made symmetric by the analysis.
The default value is OFF.
thicknessType
A SymbolicConstant specifying the distribution used for defining the thickness of the
elements. Possible values are UNIFORM, ANALYTICAL_FIELD, DISCRETE_FIELD,
NODAL_ANALYTICAL_FIELD, and NODAL_DISCRETE_FIELD. The default value is UNIFORM.
preIntegrate
A Boolean specifying whether the shell section properties are specified by the user
prior to the analysis (ON) or integrated during the analysis (OFF). The default value is
OFF.
poissonDefinition
A SymbolicConstant specifying whether to use the default value for the Poisson's ratio.
Possible values are:DEFAULT, specifying that the default value for the Poisson's ratio
is 0.5 in an Abaqus/Standard analysis and is obtained from the material definition in an
Abaqus/Explicit analysis.VALUE, specifying that the Poisson's ratio used in the analysis
is the value provided in *poisson*.The default value is DEFAULT.
poisson
A Float specifying the Poisson's ratio. Possible values are −1.0 ≤≤ *poisson* ≤≤ 0.5.
This argument is valid only when *poissonDefinition*=VALUE. The default value is 0.5.
integrationRule
A SymbolicConstant specifying the shell section integration rule. Possible values are
SIMPSON and GAUSS. The default value is SIMPSON.
temperature
A SymbolicConstant specifying the mode used for temperature and field variable input
across the section thickness. Possible values are GRADIENT and POINTWISE. The default
value is GRADIENT.
idealization
A SymbolicConstant specifying the mechanical idealization used for the section
calculations. This member is only applicable when *preIntegrate* is set to ON. Possible
values are NO_IDEALIZATION, SMEAR_ALL_LAYERS, MEMBRANE, and BENDING. The default value
is NO_IDEALIZATION.
nTemp
None or an Int specifying the number of temperature points to be input. This argument is
valid only when *temperature*=POINTWISE. The default value is None.
thicknessModulus
None or a Float specifying the effective thickness modulus. This argument is relevant
only for continuum shells and must be used in conjunction with the argument *poisson*.
The default value is None.
useDensity
A Boolean specifying whether or not to use the value of *density*. The default value is
OFF.
density
A Float specifying the value of density to apply to this section. The default value is
0.0.
layupName
A String specifying the layup name for this section. The default value is an empty
string.
thicknessField
A String specifying the name of the AnalyticalField or DiscreteField object used to
define the thickness of the shell elements. The *thicknessField* argument applies only
when *thicknessType*=ANALYTICAL_FIELD or *thicknessType*=DISCRETE_FIELD. The default
value is an empty string.
nodalThicknessField
A String specifying the name of the AnalyticalField or DiscreteField object used to
define the thickness of the shell elements at each node. The *nodalThicknessField*
argument applies only when *thicknessType*=NODAL_ANALYTICAL_FIELD or
*thicknessType*=NODAL_DISCRETE_FIELD. The default value is an empty string.
Returns
-------
A CompositeShellSection object.
