Constructs a HAT1 section.

Constructs a HAT1 section with the bottom plate’s bottom center at the origin (0, 0), with five parameters defining dimensions.

Parameters:

• dim_1 (float) – Width(x) of the HAT1-section

• dim_2 (float) – Depth (y) of the HAT1-section

• dim_3 (float) – Width (x) of hat’s top flange

• dim_4 (float) – Thickness of hat stiffener

• dim_5 (float) – Thicknesss of bottom plate

• material (Material) – Material to associate with this geometry. Defaults to pre.DEFAULT_MATERIAL.

Returns:

HAT1 section geometry

Return type:

Geometry

Example

The following example creates a HAT1 cross-section with a depth of 2.0 and width of 4.0:

from sectionproperties.pre.library import nastran_hat1

nastran_hat1(
    dim_1=4.0, dim_2=2.0, dim_3=1.5, dim_4=0.1875, dim_5=0.375
).plot_geometry()
