How to create a material

Objective:

Learn how to create a material with specific properties. 

Applies to:

  • Design analysis, topology optimization

Procedure:

There are two options for materials in nTop, Isotropic or Orthotropic. Isotropic materials have the same properties in every direction, whereas orthotropic materials have properties that vary in three directions. An example of an orthotropic material is wood and an example of an isotropic material is steel. 

nTopology also has a selection of sample materials under the Design Analysis section in the Ribbon. 

1. Figure out if your material is isotropic or orthotropic and add the correct block. In this example, we are going to be building Inconel 625, an isotropic material. 

    • Add an Isotropic Material block

2. Determine which properties you want to use:

    • Linear Elastic Property
      • Young's modulus
      • Poisson's Ratio
    • Coefficient of Thermal Expansion
      • Alpha
    • Thermal Property
      • Conductivity
      • Specific heat

3. Add the Property blocks to the Isotropic Material Property List. Use the '+' to add more inputs to the list. 

    • Add in the Linear Elastic Property
    • Add the Isotropic Thermal Property

4. Add the values for each input to create the material.

If you are going to be using a material quite often, we recommend creating the material in a standalone Notebook and saving it as a Custom block with no inputs. 

And that’s it! You’ve successfully created a material
