Constructs an elliptical hollow section (EHS).

Constructs an elliptical hollow section (EHS) centered at the origin (0, 0), with outer horizontal diameter d_x, outer vertical diameter d_y and thickness t, using n points to construct the inner and outer ellipses.

Parameters:

  • d_x (float) – Diameter of the ellipse in the x-dimension

  • d_y (float) – Diameter of the ellipse in the y-dimension

  • t (float) – Thickness of the EHS

  • n (int) – Number of points discretising the inner and outer ellipses

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

Raises:

RuntimeError – If the geometry generation fails

Returns:

Elliptical hollow section geometry

Return type:

Geometry

Example

The following example creates an EHS discretised with 30 points, with an outer horizontal diameter of 50 mm, outer vertical diameter of 25 mm and thickness of 2 mm:

from sectionproperties.pre.library import elliptical_hollow_section

elliptical_hollow_section(d_x=50, d_y=25, t=2, n=64).plot_geometry()
