Constructs a GBOX section.

Constructs a GBOX section with the center at the origin (0, 0), with six parameters defining dimensions.

Parameters:

  • dim_1 (float) – Width (x) of the GBOX-section

  • dim_2 (float) – Depth (y) of the GBOX-section

  • dim_3 (float) – Thickness of top flange

  • dim_4 (float) – Thickness of bottom flange

  • dim_5 (float) – Thickness of webs

  • dim_6 (float) – Spacing between webs

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

Returns:

GBOX section geometry

Return type:

Geometry

Example

The following example creates a GBOX cross-section with a depth of 2.5 and width of 6.0:

from sectionproperties.pre.library import nastran_gbox

nastran_gbox(
    dim_1=6.0, dim_2=2.5, dim_3=0.375, dim_4=0.25, dim_5=0.625, dim_6=1.0
).plot_geometry()
