Semi‐analytical solution for the stability of deep vertical shaft considering time‐dependent rock‐structure interaction

open access: yesDeep Underground Science and Engineering, EarlyView.
A novel cavity contraction solution and multilayer shaft wall model were developed to analyze deep shaft stability, considering rock viscosity, support structures, and water pressure, with successful validation through a Hulusu Coal Mine case study.

Fracture and fatigue in osteocytes

Journal of the Mechanical Behavior of Biomedical Materials, 2014
Fatigue is a common mode of mechanical failure which occurs when a material is subjected to repeated cycles at a strain level less than that needed for monotonic fracture. Fatigue has been observed and measured in many different materials but, until recently, not in cells.

Patellar fatigue fractures

Skeletal Radiology, 1996
Three cases of patellar fatigue fracture are reviewed. Two fractures presented with acute displacement and were initially thought to represent pathological fractures. Histological appearances in one case, and the clinical course in another, subsequently indicated that these were fatigue fractures.

Stress (Fatigue) Fractures

Postgraduate Medicine, 1968
Some persons fracture bones (most often the tibia in children and metatarsals in adults) when they undertake a strenuous, new, repetitive activity. Such fractures are simple, closed and uncomplicated. They usually heal after the activity is stopped.

FATIGUE FRACTURES OF THE FIBULA

The Journal of Bone and Joint Surgery. British volume, 1948
1. A hope expressed in 1940, that further cases of spontaneous fracture of the lowest third of the apparently normal fibula would be described, has been fulfilled. The literature is here reviewed. Five further personal cases are added. 2. The clinical and radiographic features, diagnosis, treatment and results are considered in the light of the ...

FATIGUE FRACTURES OF THE ULNA

The Journal of Bone and Joint Surgery. British volume, 1955
1. Two cases of fatigue fracture of the ulna are reported. 2. Three cases previously reported are reviewed and a striking similarity with one of the present cases is noted. 3. In all cases the mechanism of injury appears to have been the same.

Fatigue fractures of the foot

Injury, 1990
While fatigue fractures are common in military practice they are much less so in civilian practice and thus tend to be overlooked. Fractures occur most commonly in the distal second and third metatarsal shafts and within the calcaneum, but occur in almost any other bone of the foot.

Fracture and Fatigue

1988
Abstract : In the last twenty years, much progress has been made with the continuum mechanics characterization of crack growth rates through the application of linear elastic and elastic-plastic fracture mechanics, and such analyses are now in widespread use for defect-tolerant design codes.
