Numerical Simulation Research on the Interactive Propagation of Hydraulic Fractures and Natural Fractures [PDF]
In order to study the fracture propagation behavior after the interaction between hydraulic fractures and natural fractures, the cohensive unit of Abaqus finite element software is used to simulate the influence of natural fractures in the rock on the ...

Overuse injuries in teenagers have increased in incidence in the past decades. Adequately diagnosing these injuries is a challenge ('Figures 1' and '2'), especially when unfamiliar with the specific overuse injury patterns and the development steps of ...

Approach to Stress Fractures: Report of Three Cases and Review of Literature
Stress fractures occur following repetitive and mechanical overloading of the bones. Two known subtypes are fatigue fractures and insufficiency fractures. Generally, pain in the affected bone increases with activity and decreases with rest.

Female athletes who endure physical strain on the same bone area are prone to stress fractures. Preventing these improves their quality of life. Blood vitamin B2 (V.B2) and E (V.E) levels influence blood homocysteine (Hcy) levels, which, when elevated ...

Simulation of subseismic joint and fault networks using a heuristic mechanical model [PDF]
Flow simulations of fractured and faulted reservoirs require representation of subseismic structures about which subsurface data are limited. We describe a method for simulating fracture growth that is mechanically based but heuristic, allowing for ...

Characterizing Natural Fractures and Their Interactions with Hydraulically Induced Fractures [PDF]
Natural fractures are preexisting micro-cracks and fissures that can have a critical impact on hydraulic fracture treatments in shales. Most shale formations contain natural fractures, but the characteristics of these natural fractures can vary ...

Stress fractures have traditionally been classified into three categories: fatigue fractures due to overuse of bone with normal elastic resistance; insufficiency fractures due to everyday physiological stress on fragile bone with poor elastic resistance;

Post-injection normal closure of fractures as a mechanism for induced seismicity [PDF]
Understanding the controlling mechanisms underlying injection-induced seismicity is important for optimizing reservoir productivity and addressing seismicity-related concerns related to hydraulic stimulation in Enhanced Geothermal Systems.

Simulating spatial and temporal evolution of multiple wing cracks around faults in crystalline basement rocks [PDF]
Fault zones are structurally highly spatially heterogeneous and hence extremely complex. Observations of fluid flow through fault zones over several scales show that this structural complexity is reflected in the hydrogeological properties of faults ...
