Mechanics of Natural Solids

Our fluid environment (the atmosphere, oceans, rivers, etc. ) is responsible for climate, hurricanes, floods and other phen- ena characterised by rapid changes. These have to be contrasted with the permanence of our solid underground made of soil, rock, ice and snow. However, this permanence is only apparent as shown for example by earthquakes and landslides, but also by a number of other processes of deformation. Such processes are nowadays of high importance whenever we look to the future (think for example of disposal of radioactive waste or carbon dioxide) or to the past (prospectionof oil, gas and ore). But also short range extrapolations are important if we look e. g. at the prediction and mitigation of landslides or the foundation of oil and gas production plants offshore or on glaciers. Geosciences are pronouncedly multidisciplinary as they comprise perhaps the most widespread collection of disciplines, such as geology, geophysics, physics, geochemistry, geography, geotechnical and geoenvironmental engineering, Unfor petroleum engineering, soil mechanics and rock mechanics, often these disciplines operate rather independent of each other andthe increasing quest for transdisciplinary exchange is inhibited by the different languages and views prevailing in the various disciplines. It appears thus that mechanics could over a substantial link across disciplines, at least with respect to geotechnical engineering and geology.
