Constructs a CHAN2 section.

Constructs a CHAN2 (C-Channel) section with the bottom web’s middle center at the origin (0, 0), with four parameters defining dimensions.

Parameters:

  • dim_1 (float) – Thickness of channels

  • dim_2 (float) – Thickness of web

  • dim_3 (float) – Depth (y) of CHAN2-section

  • dim_4 (float) – Width (x) of CHAN2-section

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

Returns:

CHAN2 section geometry

Return type:

Geometry

Example

The following example creates a CHAN2 cross-section with a depth of 2.0 and width of 4.0:

from sectionproperties.pre.library import nastran_chan2

nastran_chan2(dim_1=0.375, dim_2=0.5, dim_3=2.0, dim_4=4.0).plot_geometry()
