'This timely textbook meets a major world-wide need in education. The author correctly identifies mechanics as both the basis for understanding the complex response of the subsurface to natural or man- made forces, and as the lingua franca for effective dialog between geoscientists and engineers. The observations of behavior over a wide range of spatial and temporal scales is critical ... Read moresince many of the features of a rock mass cannot be replicated in a classical laboratory. Global demand for subsurface resources will certainly grow, and universities must equip graduates with the skills to meet this demand. Professor Cornet's book provides an excellent foundation upon which to build the necessary expertise.' Charles Fairhurst, Professor Emeritus, University of Minnesota; Senior Consultant, Itasca Consulting Group, Inc. 'This book provides an excellent theoretical treatment of contemporary geomechanics - solid, fluid and thermal interactions in rocks accommodating rheology and rupture for static through dynamic conditions. Although presented at a high level, concepts are eminently accessible and aided by examples to highlight relevance in both geophysics and in engineering. This is destined to become a standard reference text for serious scholars spanning pure and applied geophysics through engineering geomechanics, with application to a process-based understanding in natural and engineered systems.'
