Constructs Nastran’s cruciform section.

Constructs Nastran’s cruciform cross-section with the intersection’s middle center at the origin (0, 0), with four parameters defining dimensions.

Parameters:

  • dim_1 (float) – Twice the width of horizontal member protruding from the vertical center member

  • dim_2 (float) – Thickness of the vertical member

  • dim_3 (float) – Depth (y) of the CROSS-section

  • dim_4 (float) – Thickness of the horizontal members

  • material (Material) – Material to associate with this geometry

Returns:

Cruciform section geometry

Return type:

Geometry

Example

The following example creates a cruciform cross-section with a depth of 3.0:

from sectionproperties.pre.library import nastran_cross

nastran_cross(dim_1=1.5, dim_2=0.375, dim_3=3.0, dim_4=0.25).plot_geometry()
