Steel Material

A nested class within Material used to create steel materials.

Standard

Material.STEEL(name='', standard='', db='', id=0)

Creates a steel material from database with specified standard and database code.

Parameters

  • name (default=''): Material name
  • standard (default=''): Standard code (e.g., "EN(S)", "AISC(S)", "IS(S)")
  • db (default=''): Database material code
  • id (default=0): Manual ID assignment

Object Attributes

  • ID (int): The ID of the material.
  • DATA (dict): A dictionary containing the material properties. Specific keys include:
  • TYPE (str): "STEEL"
  • NAME (str): Name of the material.
  • PARAM (list): List containing a dictionary with:
  • P_TYPE (int): 1 (for DB material).
  • STANDARD (str): Name of the standard (e.g., "EN05(S)").
  • DB (str): Name of the material in the database (e.g., "S450").

Examples

# Create steel material from database
Material.STEEL("S450 Steel", "EN05(S)", "S450", 4)
Material.STEEL("Fe540 Steel", "IS(S)", "Fe540", 5)

Material.create()

User-Defined

Material.STEEL.User(name='', E=0, pois=0, den=0, mass=0, therm=0, id=0)

Creates a user-defined steel material with custom properties.

Parameters

  • name (default=''): Material name
  • E (default=0): Elastic modulus
  • pois (default=0): Poisson's ratio
  • den (default=0): Density
  • mass (default=0): Mass density
  • therm (default=0): Thermal expansion coefficient
  • id (default=0): Manual ID assignment

Object Attributes

  • ID (int): The ID of the material.
  • DATA (dict): A dictionary containing the material properties. Specific keys include:
  • TYPE (str): "STEEL"
  • NAME (str): Name of the material.
  • PARAM (list): List containing a dictionary with:
  • P_TYPE (int): 2 (for user-defined).
  • ELAST (float): Modulus of elasticity.
  • POISN (float): Poisson's ratio.
  • THERMAL (float): Thermal coefficient.
  • DEN (float): Density.
  • MASS (float): Mass (if density is not provided).

Examples

# Create user-defined steel material
steel_user = Material.STEEL.User("Custom Steel", E=200000, pois=0.3, den=78.5, mass=7.85, therm=1.2e-5, id=6)
