Evaluation of mode I fracture toughness of cortical bone tissue in the RL crack propagation system
In this work the mode I fracture properties of bone tissue were determined for the RL propagation system. With this aim, Double Cantilever Beam (DCB) fracture tests were performed using specimens of cortical bone tissue harvested from bovine femurs with an age of approximately 8 months. In order to overcome the difficulty associated to the monitoring of crack length during propagation in the co...
متن کاملDetermination of Mode I Fracture Toughness of Cortical Human Bone Using the Dcb Test
The fracture behaviour of human cortical bone was analysed considering a miniaturized version of the Double Cantilever Beam (DCB) test. A specific data reduction scheme based on crack equivalent concept was used to obtain the resistance curves. The definition of the cohesive laws mimicking the fracture process was performed measuring the crack tip opening displacement by digital image correlati...
متن کاملStudy of Cutting Temperature in Orthogonal Milling
Finite Element Method (FEM) based techniques are available to simulate metal cutting processes and offer several advantages including prediction of tool forces, distribution of stresses, and temperatures, estimation of tool wear, and residual stresses on machined surfaces, optimization of cutting tool geometry, and cutting conditions. However, work material flow stress and friction characterist...
متن کاملThe significance of crack-resistance curves to the mixed-mode fracture toughness of human cortical bone.
The majority of fracture mechanics studies on the toughness of bone have been performed under tensile loading. However, it has recently been shown that the toughness of human cortical bone in the transverse (breaking) orientation is actually much lower in shear (mode II) than in tension (mode I); a fact that is physiologically relevant as in vivo bone is invariably loaded multiaxially. Since bo...
متن کاملRegression Analysis of Fracture Toughness for Secondary Osteons Located in Human Cortical Bone
An experiment was carried out in order to locate and quantify osteon types within a sample of cortical bone taken from a human tibia. This was done using a microscope-camera assembly and the BioQuant computer software. The results of this were correlated with a previous experiment's results on fracture toughness so that an analysis could be run on the data in order to determine the factors that...
