Overview

Simcoon provides a comprehensive library of constitutive models organized into three main categories:

• Finite Strain Models: Hyperelastic models for large deformations

• Mechanical Models: Small strain mechanical models (elasticity, plasticity, damage)

• Thermomechanical Models: Coupled thermal-mechanical models
