Model for Calculating Impact Force for Individualized Hip Fracture Prediction During a Fall [PDF]
Advances in OrthopedicsOsteoporotic-related weakening of bone is a common cause of hip fractures. The standard of care for the diagnosis and management of osteoporosis is the dual-energy x-ray absorptiometry bone mineral density T-scores.

Atomistic configurational forces in crystalline fracture [PDF]
Forces in Mechanics, 2021 Configurational atomistic forces contribute to the configurational mechanics (i.e. non-equilibrium) problem that determines the release of total potential energy of an atomistic system upon variation of the atomistic positions relative to the initial atomic configuration.

Structural formation and evolution mechanisms of fracture plugging zone
Petroleum Exploration and Development, 2021 A coupled CFD-DEM method is used to simulate the formation process of fracture plugging zone. A photo-elastic system characterizing mesoscale force chain network developed by our own is used to model the pressure evolution in fracture plugging zone to ...

Forces Required for Isolated Malleus Shaft Fractures
Otology & Neurotology, 2021 Background and Hypothesis: Isolated malleus shaft fractures are rare cases. A commonly reported cause is a finger pulled out from a wet outer ear canal after a shower or bath. The objective was to investigate experimentally the mechanism and forces needed to establish an isolated malleus shaft fracture.

Nonadiabatic Study of Dynamic Electronic Effects during Brittle Fracture of Silicon [PDF]
, 2012 It has long been observed that brittle fracture of materials can lead to emission of high energy electrons and UV photons, but an atomistic description of the origin of such processes has lacked.

Forceful sneeze: An uncommon cause of laryngeal fracture
Radiology Case Reports, 2021 Laryngeal fractures are generally induced by direct blunt or penetrating trauma to the neck. Coughing vigorously or sneezing forcefully is extremely rare causes of laryngeal fractures, with only 4 cases found after thorough literature search. Herein we present a case of a 34-year-old male presenting to the ENT emergency room with throat pain ...
