Fracture (geology) - Wikipedia

Fracture in rock is a 3D process with cracks growing in all directions. It is also important to note that once the crack grows, the microcracks in the brittle process zone are left behind leaving a weakened section of rock. This weakened section is more susceptible to changes in …

Fracture Toughness - an overview | ScienceDirect Topics

The fracture toughness of rock is an important parameter for modeling fracture failure and can be measured from laboratory tests. Gunsallus and Kulhawy (1984) and Bhagat (1985) experimentally found that Mode I fracture toughnesses of several types of rocks and soils are directly proportional to their tensile strengths.

Segond fracture | Radiology Reference Article ...

Segond fracture is an avulsion fracture of the knee that involves the lateral aspect of the tibial plateau and is very frequently (~75% of cases) associated with disruption of the anterior cruciate ligament (ACL).On the frontal knee radiograph, it may be referred to as the lateral capsular sign.

Fracture (mineralogy) - Wikipedia

In the field of mineralogy, fracture is the texture and shape of a rock''s surface formed when a mineral is fractured.Minerals often have a highly distinctive fracture, making it a principal feature used in their identification. Fracture differs from cleavage in that the latter involves clean splitting along the cleavage planes of the mineral''s crystal structure, as opposed to more general ...
