Fracture mechanics deals with the strength behavior of materials and structures with cracks by applying structural mechanics and relevant fracture criteria. Basic concepts of fracture mechanics include the energy-based concept, the stress intensity-based concept and the crack growth-based concept, which can be found in many textbooks, e.g. The increased attention paid to experimental rock fracture mechanics has led to major contributions to the solving of geophysical problems. The text presents a concise treatment of the physics and mathematics of a representative selection of problems from areas such as earthquake mechanics and prediction, hydraulic fracturing, hot dry rock.

Although early approaches have striven to predict fracture by analyzing the behavior of atomic bonds, Griffith has shown in that attention should be given to the behavior of an existing crack. Fig. Tensile test with axial elongation and fracture. Fracture mechanics In fracture mechanics attention is basically focused on a single crack.

Fracture mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials. It uses methods of analytical solid mechanics to calculate the driving force on a crack and those of experimental solid mechanics to characterize the material's resistance to fracture.. In modern materials science, fracture mechanics is an important tool used to improve the. Metals -- Fracture. See also what's at your library, or elsewhere.
