In this article, failure and fracture mechanisms in an aluminum alloy (which has been used in diesel internal combustion engines), with and without ceramic thermal barrier coatings, have been investigated under isothermal and non-isothermal fatigue loadings. In this research, the base material is an aluminum-silicon-magnesium alloy and the thermal barrier coating includes a metallic bond coat l...

In this work, we used a grain-based numerical model based on the concept of lattice. The modelling was done to simulate the lab experiments carried out on the mortar samples. Also the analytical solutions corresponding to the viscosity-dominated regime were used to estimate the fracture length and width, and the results obtained were compared with the numerical simulations. As the analytical so...

This study aims to investigate the flow and fracture behavior of aluminum alloy 6082-T6 (AA6082-T6) at different strain rates and triaxialities. Two groups of Charpy impact tests were carried out to further investigate its dynamic impact fracture property. A series of tensile tests and numerical simulations based on finite element analysis (FEA) were performed. Experimental data on smooth speci...

The object of this investigation was to gain a better understanding of the flow and fracture propensity of steel plates in which the Wells-type notch served as the fracture initiator. This type of notch is of importance in experimental investigations of the brittle fracture phenomenon because it successfully initiates low-stress brittle fractures in the wide-plate specimen in which it is used. ...

A radial nerve injury associated with a humeral shaft fracture is an important injury pattern among trauma patients.This study is to find out the incidence of radial nerve palsy and to analyze results of treatment of fracture shaft of Humerus associated with radial nerve injury to improve outcome and avoid long-term morbidity.A total of eighty patients of fractures were analyzed with twenty imm...

In root-treated anterior teeth a better aesthetic can be achieved by using translucent and tooth-coloured post and core restorations instead of traditional metal post systems. The aim of this in vitro study was to compare the fracture strength of tooth-coloured ceramic and fibre-reinforced posts as well as titanium posts with clinically proven gold alloy posts as a control. Two all-ceramic, one...

Fracture of Tibia is the most common amongst pediatric fractures. Most tibial shaft fractures are treated conservatively with close reduction and above knee cast application. Surgery is indicated only when the fracture is unstable, open fracture and associated with multiple injuries. Flexible intramedullary nailing is commonly used for diaphyseal tibial fracture and is also well used in other l...

The aim of the study was to assess the change in function and residential status four months after hip fracture in patients over 50 years of age and living independently at home at the time of fracture. All consecutive hip fracture patients treated at Oulu University Hospital during 1989--1999 were followed up. Data collection was done on standardized hip fracture forms, which were filled in at...

PURPOSE To evaluate the predictive factors for development of diplopia and extraocular muscle movement (EOM) limitations in the patients with isolated pure blow-out fracture. METHODS One hundred thirty-two patients with isolated pure blow-out fracture were included. The diagnosis was done with computed tomography scan. Possible predictive factors were analyzed with logistic regression. The ca...
