MembraneSection object

The MembraneSection object defines the properties of a membrane section.

The MembraneSection object is derived from the Section object.

MembraneSection(...)

This method creates a MembraneSection object.

Path

mdb.models[name].MembraneSection
session.odbs[name].MembraneSection

Required arguments

name

A String specifying the repository key.

material

A String specifying the name of the material.

Optional arguments

thickness

A Float specifying the thickness for the section. Possible values are thickness > 0.0. The default value is 1.0.

thicknessType

A SymbolicConstant specifying the distribution used for defining the thickness of the elements. Possible values are UNIFORM, ANALYTICAL_FIELD, and DISCRETE_FIELD. The default value is UNIFORM.

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 section 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.

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.

Return value

A MembraneSection object.

Exceptions

RangeError and InvalidNameError.

setValues(...)

This method modifies the MembraneSection object.

Required arguments

None.

Optional arguments

The optional arguments to setValues are the same as the arguments to the MembraneSection method, except for the name argument.

Return value

None.

Exceptions

RangeError.

Members

The MembraneSection object has members with the same names and descriptions as the arguments to the MembraneSection method, except for the thicknessType and thicknessField arguments.

In addition, the MembraneSection object can have the following member:

rebarLayers

A RebarLayers object specifying reinforcement properties.
