Specimen-specific Modelling of Cervical Vertebrae in Axial Compression
INTRODUCTION Finite element (FE) models of the cervical spine are needed to evaluate injury prevention devices and to improve our understanding of vertebra fractures, which may injure the spinal cord. However, current FE cervical spine models typically do not incorporate trabecular bone heterogeneity or geometrical differences between spines; therefore, the models are not able to address questi...
متن کاملDynamic Compression-shear Response of Brittle Materials with Specimen Recovery
-A new configuration for compression-shear soft-recovery experiments is presented. This technique is used to investigate various failure mechanisms during dynamic multiaxial loading of an AI203/SiC nanocomposite and TiB2. Velocity profiles of the target surface are measured with a variable sensitivity displacement interferometer, yielding normal and transverse velocity-time histories. A dynamic...
متن کاملPrediction of Temperature Distribution in the Hot Torsion Test Specimen
Hot torsion test (HTT) has extensively been used to analysis and physically model flow behavior and microstructure evolution of materials and alloys during hot deformation processes. In this test, the specimen geometry has a great influence in obtaining reliable test results. In this paper, the interaction of thermal-mechanical conditions and geometry of the HTT specimen was studied. The commer...

متن کاملNumerical Determination of Delamination Onset in Laminated Symmetric DCB Specimen
In this study, a novel numerical method is proposed for determination of mode-I interlaminar fracture toughness, GIc, in multi-directional (MD) double cantilever beam (DCB) specimens using fracture properties of unidirectional DCB specimens. Two factors, β and Dc are defined to minimize the undesirable effects on strain energy release rate. β describes the difference between maximum and average...
