steel_material

planestress.pre.library.steel_material(thickness: float, units: str = 'MPa', color: str = 'grey') → Material

Creates a steel material object with consistent units.

Parameters:

• thickness (float) – Thickness of the steel.

• units (str) – Units system to use. See below for options. Defaults to "MPa".

• color (str) – Material color for rendering. Defaults to "grey".

Raises:

ValueError – If the value of units is not in the list below.

Returns:

Steel material object.

Return type:

Material

Units

The value for units may be one of the following:

• "MPa": Newtons \([\textrm{N}]\) and millimetres \([\textrm{mm}]\).

  • Elastic modulus: \(200 \times 10^3 \textrm{ MPa}\)

  • Poisson’s ratio: \(0.3\)

  • Density: \(7.85 \times 10^{-6} \textrm{ kg/mm}`^3\)

• "SI": Newtons \([\textrm{N}]\) and metres \([\textrm{m}]\).

  • Elastic modulus: \(200 \times 10^9 \textrm{ Pa}\)

  • Poisson’s ratio: \(0.3\)

  • Density: \(7.85 \times 10^3 \textrm{ kg/m}`^3\)
