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.
