Fracture Energy of Refractories
Advanced Materials Research, 2012This paper introduce the relationship between fracture energy of refractories and its thermal shock resistance, and research status about fracture energy of refractories. It shows that investigation on fracture energy of refractories at high temperature is positive significance for evaluation of thermal shock resistance, and wedge splitting method for ...

Abstract The fracture energy of Float and Pyrex glass plates has been determined in various media using a simple double-cantilever cleavage technique. Although slow growth of the crack at constant displacement of the cantilever arms was observed in all environments, consistent values for the energy expended when the crack propagates rapidly were ...

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.

Fracture energy of bone in a shear mode
Medical & Biological Engineering, 1974The role of the osteon as the basic strengthening unit of compact bone is discussed. Using previous work on the shear strength of bone, an analysis is given enabling a computation to be made of the mode-II (debonding) fracture energy. The evidence suggests that bone, like many reinforced composites, derives its excellent fracture characteristics from ...

Pelvic fractures and high energy traumas
British Journal of Hospital Medicine, 2005Pelvic fractures are associated with a high mortality and morbidity and their presence should be considered in all high energy traumas. Early management is directed towards basic advanced trauma life support (ATLS) principles but it is essential to be aware of the diagnosis and management of these complex injuries.

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.

In this presentation problems of fracture of concrete as seen in relation to the demolition of concrete structures will be dealt with. In particular, the question arises how much energy will be required to demolish a concrete structure by mechanical means. To limit the extent of the problem we will only consider normal weight, unreinforced concrete. In

Fracture Energy Effect on Spall Signal
AIP Conference Proceedings, 2004Numerical simulations of flying plate impact test usually show discrepancies between the calculated and observed velocity vs time plot under spalling conditions. Very often these differences are ascribed either to the constitutive model or to the numerical scheme. In this paper it is shown that, at least in the case of ductile metals, these differences

High-energy tibial plateau fracture
Orthopaedics & Traumatology: Surgery & ResearchHigh-energy tibial plateau fracture is complex and hard to treat, with functional sequelae and frequent soft-tissue lesions. Several classifications, strategies, approaches and fixation techniques have been reported. High-energy trauma is defined by high-velocity impact: fall from height, high-speed road or sport accident, firearm injury, etc ...
