Fracture mechanics, Mohr circles, and the Coulomb criterion (Stress and failure)

Fracture mechanics, Mohr circles, and the Coulomb criterion (Stress and failure). Introduction to Fracture Mechanics. In this lecture, we will be focusing on faults: How they form Definitions Stress states Fault strain How we can use faults to tell us things about the geologic history

Faults I

Faults I. Fault. A fault is a mesoscopic to macroscopic plane ( listric faults are curved at large scale !) along which the two blocks on either side have displaced (slipped) relative to one another The slip is primarily due to brittle deformation

Mohr Circle for stress

Mohr Circle for stress. In 2D space (e.g., on the s 1 s 2 , s 1 s 3 , or s 2 s 3 plane), the normal stress ( s n ) and the shear stress ( s s ), could be given by equations (1) and (2) in the next slides
