Abstract:

The mechanics of porous media, or briefly poromechanics, sometimes is directly equated with Geomechanics. And this is probably also no surprise as many problems relevant for Geomaterials can be described with theories of poromechanics and also many of the involved interesting effects can be present and relevant for these applications, like large deformations of the solid skeleton, transport of different substances, interface effects on different scales etc. But it is important to note that more or less the same theory, if formulated in a sound and consistent way, can also be used – and actually is often THE appropriate theory – for many other interesting and important applications that also are essential for sustainable development.
With his strong and unique background and expertise in the Mechanics of Porous Media and Geomechanics, Bernhard Schrefler also was a pioneer in transferring this expertise to other interesting areas in different fields of Engineering and the Applied Sciences. This serves as an motivation for me to cover advanced computational models and approaches for porous media for interesting problems beyond Geomaterials.
In this talk we will present some of our recent work on advanced modeling and development of novel computational approaches in important applications, all of which also play an important role in sustainable development, namely energy storage systems as well as highly relevant biomedical and biophysical applications.
