Constructs a rectangular hollow section (RHS).

Constructs a rectangular hollow section (RHS) centered at (b/2, d/2), with depth d, width b, thickness t and outer radius r_out, using n_r points to construct the inner and outer radii. If the outer radius is less than the thickness of the RHS, the inner radius is set to zero.

Parameters:

  • d (float) – Depth of the RHS

  • b (float) – Width of the RHS

  • t (float) – Thickness of the RHS

  • r_out (float) – Outer radius of the RHS

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

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

Returns:

Rectangular hollow section geometry

Return type:

Geometry

Example

The following example creates an RHS with a depth of 100 mm, a width of 50 mm, a thickness of 6 mm and an outer radius of 9 mm, using 8 points to discretise the inner and outer radii:
