What are the material mechanical properties used in the Material Library defined in the software?

The Material Library in Cognitive Design provides a predefined set of isotropic materials used across simulation and topology optimization workflows. Each material is characterized by its density, Young’s modulus, Poisson’s ratio, and yield strength, ensuring consistent and reliable behavior in mechanical analyses.

Below is the full list of materials and their corresponding properties:
