Following the successful International Workshop on Modern Trends in Geomechanics held in Vienna in 2005, Stanford University hosted its sequel in 2010 under the theme Multiscale and Multiphysics Processes in Geomechanics. This book is a compilation of the extended abstracts from the Stanford workshop and highlights the diverse and complex processes encountered in geomechanics in terms of scale (from nanometer to kilometer) and scientific scope. Topics covered in this book include coupled physics phenomena such as thermo-poro-mechanical and electro-poro-mechanical processes, chemical species reactivity and transport, strain localization phenomena, unsaturated soils, fluid flow in porous solids, and dynamics of fault zones. The book also covers contributions dealing with the development of multiscale numerical techniques, as well as the laboratory and field investigation methods supporting these numerical techniques.

It is not an easy task to fascinate a student with a standard course on Soil Mechanics and Geotechnical Engineering. If, however, the same material is presented as a tool to explore a natural or a man-made "disaster", both the motivation and the ability to absorb this material increase dramatically. The case studies in this book could help to build an introductory Forensic Geotechnical Engineering course, covering such basic topics as settlements, bearing capacity and excavations. The failure cases considered in this book have something in common – they can be all reasonably well explained using so called "back-of-the-envelope" calculations, i.e., without sophisticated models requiring finite element analysis. These simple methods based on clear mechanical considerations are the endangered species of the computer dominated era, though sometimes they could prevent a disaster caused by a wrong application of computer models. In particular, the upper bound limit analysis has repeatedly proven itself as a powerful tool allowing for sufficiently accurate estimates of the failure loads and leaving a lot of room for creativity. No one is exempt from making mistakes, but repeating well known mistakes reveals a gap in education. One of the objectives of this book is to attempt bridging this gap, at least partially. More failure cases covering a larger area of geotechnical problems are included into the companion book "Geomechanics of Failures: Advanced Topics" by the same authors.

The book analyzes a quasi-static fracture process in concrete and reinforced concrete by means of constitutive models formulated within continuum mechanics. A continuous and discontinuous modelling approach was used. Using a continuous approach, numerical analyses were performed using a finite element method and three different enhanced continuum models: isotropic elasto-plastic, isotropic damage and anisotropic smeared crack one. The models were equipped with a characteristic length of micro-structure by means of a non-local and a second-gradient theory. So they could properly describe the formation of localized zones with a certain thickness and spacing and a related deterministic size effect. Using a discontinuous FE approach, numerical results of cracks using a cohesive crack model and XFEM were presented which were also properly regularized. Finite element analyses were performed with concrete elements under monotonic uniaxial compression, uniaxial tension, bending and shear-extension. Concrete beams under cyclic loading were also simulated using a coupled elasto-plastic-damage approach. Numerical simulations were performed at macro- and meso-level of concrete. A stochastic and deterministic size effect was carefully investigated. In the case of reinforced concrete specimens, FE calculations were carried out with bars, slender and short beams, columns, corbels and tanks. Tensile and shear failure mechanisms were studied. Numerical results were compared with results from corresponding own and known in the scientific literature laboratory and full-scale tests.    .
