Abstract
Different failure mechanisms that occur on several spatial and temporal scales have to be included in the physical modeling of material behavior for gaining a fundamental understanding of damage and failure in hard or soft materials. In particular, granular materials such as concrete or highperformance ceramics are characterized by complex failure modes and a highly anisotropic bias due to their inhomogeneous microstructure which is difficult to incorporate in traditional finite element approaches. In contrast to hard matter, i.e. materials which are mainly governed by strong covalent bonds, the mechanisms of mechanical failure in soft biomaterials, e.g. biomembranes, cellular structures or tissues is less understood. Starting from discussing various numerical approaches for modeling mechanical behavior upon shock wave load in hard matter, we provide a short review of the new emerging field of shock wave applications in macromolecular physics, biology and medicine.
