| 151-0513-00L | Mechanics of Soft Materials and Tissues | 4 KP | 3G | A. E. Ehret | |||||||||||||||||
| Kurzbeschreibung | An introduction to concepts for the constitutive modelling of highly deformable materials with non-linear properties is given in application to rubber-like materials and soft biological tissues. Related experimental methods for materials characterization and computational methods for simulation are also briefly addressed. | ||||||||||||||||||||
| Lernziel | After successful completion of the course students are able to • name important examples of the wide range of non-linear mechanical behaviours displayed by soft materials and tissues. • describe typical experimental set-ups for characterization soft materials and to critically interpret the corresponding experimental data. • explain basic physical concepts to relate the structure and mechanical properties of rubber-like materials and soft biological tissues. • discuss and safely apply mathematical concepts for modelling these materials. • explain, select and define suitable material models for rubber-like materials and soft biological tissues. • evaluate the response predicted by constitutive models in simple load cases. | ||||||||||||||||||||
