... of the existing theories do not take into account the effect of fluid penetration into the cracks. This paper proposes a simple theory, based on the Linear Elastic Fracture Mechanics (LEFM) approach, which is able to take into account these effects. It shows in particular that the effect of pressurization rate...

... salt using the single edge cracked half disc specimen (or semicircular bend specimen) in three-point loading. The experimental method and test results are given in this paper. There are many assumptions inherent in applying fracture mechanics techniques to WIPP salt, and these assumptions should...

... a solid. The phenomenological description of inhomogeneities is presented by a random field of specific fracture energy following the framework of Statistical Fracture Mechanics (SFM). A brief review of SFM is presented and application to modeling of hydraulic fracture is discussed. 1 INTRODUCTION...

Paper Number: ARMA-96-1715
... ABSTRACT ABSTRACT :A probabilistic model for failure of brittle materials under compression, based on Linear Elastic Fracture Mechanics (LEFM), is proposed herein. Crack length is taken as the model random variable. Phenomena like axial crack propagation, stable fracture propagation...

Paper presented at the 1st North American Rock Mechanics Symposium, June 1–3, 1994
Paper Number: ARMA-1994-0327
... ABSTRACT ABSTRACT: An attempt was made in this paper to apply the principles indentation fracture mechanics to disc cutting. A total of 25 disc angles varying between 60° to 100° and diameters ranging from 100 mm to 200 mm was investigated. Following the indentation tests, cutting tests were...
