Assign Properties

In this page, we will show detailed procedures of assigning material properties for frame and airbags.

Create Material: frame

Firstly, we create a new material named 'Material-frame' for the frame. And set the following properties:

  • General > Density:
    • Density = 1.2e-9 Mg/mm³
  • Mechanical > Elasticity> Elastic:
    • Young’s Modulus = 100 MPa
    • Poisson’s ratio = 0.38

property-plus-2

Create Material: airbag

For the property of airbags inside named ' Material-air bag',  set:

  • General > Density:
    • Density = 1.2e-9 Mg/mm³
  • Mechanical > Elasticity> Elastic:
    • Young’s Modulus = 1000 MPa
    • Poisson’s ratio = 0.45

property-4

Create Sections

Double click on Sections in the model tree to create a new section. Set it to be a homogeneous solid and assign 'Material-frame' as its material.

property-4
property-plus-4

Create another section and set it to be a homogeneous shell and assign 'Material-air bag' as the material. Set the shell thickness as 0.1.

Edit Section Assignment

Last, assign the section property to corresponding part by selecting the entire part geometry.
