Learning Outcomes
Competences
Students are able to understand, apply and critically evaluate the mechanical material models for polymer materials in the context of continuum mechanics. They can differentiate between various models for elastic, viscoelastic, elastoplastic and failure-based behavior of polymers and transfer them to real applications.
Skills Knowledge
In particular, they are able to

Explain the basic principles of continuum mechanics and state their significance for modeling polymeric materials [k2].

Systematically classify material models and identify their prerequisites, areas of application and limitations [k4].

Differentiate between elastic material models with increasing degrees of anisotropy and demonstrate their application [k3].

Explain hyperelastic material models for polymers and apply them to selected examples [k2, k3].

analyze viscoelastic material models for isotropic and anisotropic polymers and evaluate their influence on the mechanical behavior [k4, k5].

Understand elastoplastic material models with a focus on polymer-compatible approaches and critically reflect on their use in practice [k3, k6].

Fundamentals of continuum mechanics: Stress and distortion states, material law definitions

Classification of material models: Elastic, viscoelastic, elastoplastic, fracture mechanics
