Biological materials possess the ability to adapt according to their particular loading conditions. The course will focus on the computational continuum modeling of such phenomena, which often are denoted as growth and remodeling. As soft biological tissues such as skin, tendons, muscles, vessels usually undergo large deformations and possess a highly fibrous microstructure, continuum-mechanics-based modeling frameworks are commonly based on finite anisotropic elasticity. Combination of the specific constitutive models with the finite element method then allows to simulate general boundary value problems. In addition to standard continuum theories, enhanced by the concept of a multiplicative decomposition, the application of so-called computational micro-sphere models will be discussed in the course with application to growth as well as remodeling with focus on hard and soft biological tissues.
The participants are assumed to have a back-ground in finite deformation continuum mechanics. Some background in the finite element method is also desirable but not required.
