Fracture energy and fracture process zone
Materials and Structures, 1992The fracture energy Gf can be determined following a RILEM recommendation. However, it has been found that fracture energy depends on both size and geometry of the test specimen. The underlying fictitious crack model postulates that fracture energy, tensile strength, the critical opening of the fictitious crack, and the shape of the softening curve ...

Fracture surface energy of olivine
pure and applied geophysics, 1978A relatively simple indentation technique for the rapid measurement of fracture surface energy, Γ, of small samples is described. The reliability of this technique is assessed by testing soda-lime glass for which there are good independent fracture mechanics determinations of fracture surface energy.

Low-energy bilateral scapular fractures
Emergency Medicine Journal, 2008A 73-year-old, right-handed man attended the emergency department with a history of bilateral shoulder pain following a low-energy mechanical fall. On clinical examination he had bruising and tenderness on palpation over …

High-Energy Tibial Shaft Fractures
Orthopedic Clinics of North America, 2002High-energy tibial fractures are common injuries that are managed by most practicing orthopaedic surgeons. Many methods of treatment are available. This article reviews the options for skeletal stabilization, the risks and benefits of each, and the necessary concepts that effect outcome.

Low-energy osteoporotic pelvic fractures
Archives of Orthopaedic and Trauma Surgery, 2010The vast majority of pelvic fractures in geriatric patients are classified as stable injuries. The current treatment strategies of these fractures involve pain management and mobilization. Pain-related immobility may pose a serious hazard to patients with severe preexisting comorbidities.

Energy Dissipation in Dynamic Fracture
Physical Review Letters, 1996Measurements in PMMA of both the energy flux into the tip of a moving crack and the total surface area created via the microbranching instability indicate that the instability is the main mechanism for energy dissipation by a moving crack in brittle, amorphous material. Beyond the instability onset, the rate of fracture surface creation is proportional

High-Energy Tibial Plateau Fractures
Journal of the American Academy of Orthopaedic Surgeons, 2006The severity of a tibial plateau fracture and the complexity of its treatment depend on the energy imparted to the limb. Low-energy injuries typically cause unilateral depression-type fractures, whereas high-energy injuries can lead to comminuted fractures with significant osseous, soft-tissue, and neurovascular injury.

Imaging of low-energy vertebral fractures
Radiología (English Edition), 2023Low-energy vertebral fractures pose a diagnostic challenge for the radiologist due to their often-inadvertent nature and often subtle imaging semiology. However, the diagnosis of this type of fractures can be decisive, not only because it allows targeted treatment to prevent complications, but also because of the possibility of diagnosing systemic ...
