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 ...

Journal of Materials Science, 1985
The fracture energy of Si3N4 made by hot pressing, reaction sintering, and chemical vapour deposition (CVD) was studied. Extrapolation of fracture energies to zero additive or porosity levels, as well as analysis of CVD Si3N4 all indicate an intrinsic fracture energy of 20–30J m−2.

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 ...

Fracture energy and fracture toughness of concrete
Magazine of Concrete Research, 1994The stress intensity factor for a specimen used for fracture toughness testing of cementitious materials was obtained by the finite element method using isoparametric representations and two energy approaches. A range of specimen geometrise were considered and the critical strain energy release rate Gc, and critical value of an energy integral Jc were

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.

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

The fracture energy of bimaterial interfaces
Materials Science and Engineering: A, 1990This article describes a framework applicable to the measurement and interpretation of the fracture energy of bimaterial interfaces. A major conclusion of this study is that the fracture energy, Γi, is not unique and usually exhibits values substantially larger than the thermodynamic “work of adhesion. ” The lack of uniqueness is related to mode mixity

Distraction osteogenesis through high energy fractures
Injury, 1998We present a series of three patients with segmental, high energy open tibial fractures with bone loss (2-7 cm), where we have used distraction through a fracture site to replace lost bone. The open fracture was treated by debridement and shortening to eliminate the bone and soft tissue defect. Limb length was restored by distraction instituted through

1981
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

Composite Interlaminar Fracture: Effect of Matrix Fracture Energy
Journal of Composites Technology and Research, 1984A major result of the use of the double cantilever beam test to provide a measure of the interlaminar fracture energy in composites subjected to simple Mode I-type loading is the observation that increasing the toughness of the matrix resin by as much as a factor of 20 produced a major (approximately four-fold) increase in interlaminar fracture energy.
