This workshop was run under the motto to bring together di?erent schools of thought in geomechanics research. The workshop was attended by about 50 participants from 15 countries. Besides the presentations, the workshop also o?ered welcoming occasions for stimulating discussions. The contributions in this book cover a wide range of topics from applied mathematics to geoengineering applications, re?ecting the breadth and depth of geomechanics research. The articles are peer reviewed and arranged in six parts: general aspects, constitutive modelling, micromechanics, analytical and numerical methods, granular materials and engineering applications.
