International Symposium in honor of Professor Gerhard A. Holzapfel’s 60th birthday
30.06.2022: Biomechanics:
Challenges of the Next Decade, Graz, June 30 – July 1, 2022
Prof. Dr.-Ing. Daniel Balzani gives talk about Mesh-independent simulation of damage in soft biological tissues
Objectives of the symposium
Biomechanics is a challenging subject that studies living systems by means of the development, extension, and application of mechanics to better understand biological, engineering and medical phenomena. Nonlinear continuum mechanics, multiscale modeling, advanced 3D imaging techniques together with unprecedented predictive computational power allow us to solve cutting-edge biomechanics problems with rather complex patient-specific anatomies.
Interdisciplinary approaches that address phenomena at the nano-, micro-, or macro-levels are often required to solve such problems. Mechanics, natural sciences such as biophysics, biochemistry, and mathematics, as well as biomedical-, tissue-, health care-, computer- and biomolecular engineering sciences need to be combined with medicine to tackle real-world problems.
This symposium aims to gather the expertise of established and emerging scientists with backgrounds in the relevant areas of solid (bio)mechanics. It will highlight the state-of-the-art research in mathematical modeling, computational simulation, and experimental methods for testing of a range of biological tissues. In addition, it will highlight some major challenges of the next decade and how we can be better prepared for them.
