Modeling and simulation of wood forming processes
Thermo-hygro-mechanical processes for densification and forming of wood:
Continuum-mechanical material modeling and structural simulation
Research topics
- Phenomenological description of constitutive characteristics of the wood forming process
- Development of realistic, macroscopic, numerical tool for modeling wood by using an invariant-based anisotropic elasto-plastic material model for wood at large deformations
- Consideration of the influence of temperature and moisture, e.g. by a thermal hygroscopic finite surface element and constitutive formulations
- Parameter identification by comparison of experiments and simulations
- Industry- and application-related simulation of structures made from formed wood by means of the finite element method
