axis : --is-rst--:py:class:`~abaqus.UtilityAndView.SymbolicConstant.SymbolicConstant` = 'AXIS_3'[源代码]¶: A SymbolicConstant specifying the axis of a cylindrical or spherical datum coordinate system about which an additional rotation is applied. For shells this axis is also the shell normal. This only applies if a valid reference is provided for the orientation. Possible values are AXIS_1, AXIS_2, and AXIS_3. The default value is AXIS_3.

material : --is-rst--:py:class:`str`[源代码]¶: A String specifying the name of the section layer material.

numIntPts : --is-rst--:py:class:`int` = 3[源代码]¶: An Int specifying the number of integration points to be used through the section. This argument is valid only if the preIntegrate argument on the parent CompositeShellSection object is set to ON. The default value is 3.

orientAngle : --is-rst--:py:class:`float` = 0[源代码]¶: A Float or a String specifying the relative orientation of the section layer. A Float specifies the angular orientation; a String specifies a user-subroutine orientation name. If a String is specified, a user-subroutine orientation is used, otherwise the Float value is used as an angular orientation. The default value is 0.0.

orientation : --is-rst--:py:class:`~abaqus.UtilityAndView.SymbolicConstant.SymbolicConstant`[源代码]¶: The SymbolicConstant None or a DatumCsys object specifying a coordinate system reference for the relative orientation of this layer. If this reference is valid it is used as the relative orientation of the layer, otherwise the orientAngle is used as described. The default value is None.

plyName : --is-rst--:py:class:`str` = ''[源代码]¶: A String specifying the ply identifier for this section layer. The default value is “”.

thickness : --is-rst--:py:class:`float`[源代码]¶: A Float specifying the thickness of the section layer.

thicknessType : --is-rst--:py:class:`~abaqus.UtilityAndView.SymbolicConstant.SymbolicConstant` = 'THICKNESS_MAGNITUDE'[源代码]¶: A SymbolicConstant specifying the method used to describe the thickness. Possible values are THICKNESS_MAGNITUDE and THICKNESS_DISCRETE_FIELD. The default value is THICKNESS_MAGNITUDE.
