Constructs an angle section.

Constructs an angle section with the bottom left corner at the origin (0, 0), with depth d, width b, thickness t, root radius r_r and toe radius r_t, using n_r points to construct the radii.

Parameters:

• d (float) – Depth of the angle section

• b (float) – Width of the angle section

• t (float) – Thickness of the angle section

• r_r (float) – Root radius of the angle section

• r_t (float) – Toe radius of the angle section

• n_r (int) – Number of points discretising the radii

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

Returns:

Angle section geometry

Raises:

ValueError – If the toe radius is larger than the toe thickness

Return type:

Geometry

Example

The following example creates an angle section with a depth of 150 mm, a width of 100 mm, a thickness of 8 mm, a root radius of 12 mm and a toe radius of 5 mm, using 16 points to discretise the radii:

from sectionproperties.pre.library import angle_section

angle_section(d=150, b=100, t=8, r_r=12, r_t=5, n_r=16).plot_geometry()
