Aspects of Mechanical Behavior of Rock under Static and Cyclic Loading. Part A. A One-Dimensional Progressive Failure Model of Rock. Part B. Mechanical Behavior of Rock under Cyclic Fatigue

Abstract

It is well known that the strength and deformation properties of rock are highly variable. It has also been observed that rock does not fail in a weakest link manner but progressively, maintaining considerable load-bearing capacity beyond its peak load. It is hypothesized that the variability of properties and progressive failure behavior are direct consequences of the statistical inhomogeneity of the material. A one-dimensional model is used to demonstrate that progressive failure can indeed result from inhomogeneity of the material and to show what the effects of varying statistical distributions of properties might be on the gross deformation and failure of rock.
