====== Supported Materials ======

Intact.design provides many material options, organized into six main groups: \\
  * **Ferrous metals** 
    * Contain iron and are usually magnetic. Used for their high tensile strength and durability.  
  * **Non-ferrous metals** 
    * Lighter and more malleable than ferrous metals. These materials do not exhibit typical properties of metals such as hardness and conductivity.
  * **Non-metals** 
    * Includes materials such as concrete, glass, and rubber.
  * **3D printed plastics** 
    * Inexpensive materials used in the 3D printing process.
  * **Engineering plastics** 
    * Harder and more durable plastics than 3D printed ones
  * **Biological materials** 
    * Different types of bones are currently supported


For a list of all the materials with their properties, download this **[[https://docs.google.com/spreadsheets/d/1pPP2sgpejghNadWGEhvhQryvVVgAhTZx6QBDA1GSFro/edit#gid=1832695137|excel sheet]]**.
In the Excel sheet, there are several lines to understand
  - Material name
  - Category: Ferrous metal, non-ferrous metal, non-metal, 3D printed plastic, engineering plastic (Organized by category in Intact.design)
  - Failure criterion: a way to measure how and under what conditions a material will fail. Materials either fracture (brittle failure) or yield (ductile failure). There are several failure criterion methods for each type of failure. 
  - Density: defined by mass/volume
  - Elastic modulus: derived from the linear (elastic) region of the stress-strain curve; a measure of a material’s resistance to being deformed when a force is applied to it.
  - Poisson’s ratio: negative ratio of lateral strain to longitudinal strain.
  - Yield Strength: stress at which a material begins to deform plastically
  - Tensile Strength: the maximum stress a material can withstand before breaking while being pulled apart
  - Compressive strength: the maximum stress a material can withstand before breaking when being compressed
