Since the publication of the first edition in 1969, Fundamentals of Rock Mechanics has been widely regarded as the most authoritative and comprehensive book in its field. This classic book, unavailable for many years, is now back by popular demand. Extensively revised for this fourth edition, it now contains substantially expanded chapters on poroelasticity, wave propagation, and subsurface stresses, as well as entirely new chapters on rock fractures and micromechanical models of rock behavior. Beginning with a detailed discussion of fundamental concepts such as stress and strain, this classic text offers a thorough introduction to the subject of rock mechanics, before expertly delving into a fundamental, self-contained discussion of specific topics. Unmatched in the breadth of its treatment, the new edition of this highly praised text is an invaluable resource for all geologists, geophysicists, and geotechnical engineers working in the field today.
