Define Materials
Assign materials from the database or define custom values in Dr.Q.
If you only have 2 minutes
Assign a material to every solid body in your model — either from the built-in database or by entering custom values.
Material database
Dr.Q includes a database of common engineering materials:
| Material | Young's modulus (MPa) | Poisson's ratio | | --- | --- | --- | | Structural steel S235 | 210,000 | 0.30 | | Aluminium AlMg3 | 70,000 | 0.33 | | Titanium Ti-6Al-4V | 114,000 | 0.34 |
Custom materials
You can define custom materials by entering your own values for Young's modulus, Poisson's ratio, and density.
Make sure your material values are in consistent units. Dr.Q works in MPa (N/mm²) by default. A common mistake is entering Young's modulus in GPa — 210 GPa looks right but is 1000× too small in the MPa unit system.
