Isotropic Nd-Fe-B thick-film magnets have been prepared using a pulsed laser deposition (PLD) method with the control of laser energy density (LED) followed by post-annealing. The characteristics of the method are a high deposition rate up to several tens of microns per hour together with a reliability of magnetic properties due to the good transfer of composition from an Nd-Fe-B target to a fi...

Abstract. The mechanical and damage behavior of a X100 steel after prestrain is studied in this work. Experimental results show both a plastic and rupture anisotropy: the T direction exhibits a higher ultimate stress but the lowest ductility and toughness. Prestrain reduces ductility and crack growth resistance. A model able to represent the plastic and damage behaviour of the material before a...

The aim of the project was to create finite element model of a commercially available wrist implant to examine its behaviour under loading. The finite element model was validated by carrying out mechanical tests. Little is known about the mechanics of wrist implants under loading and how they interact with the surrounding bone. Surgical outcomes have been poor and further research is needed to ...

Solid-extracellular fluid interaction is believed to play an important role in the strain-rate dependent mechanical behaviors of shoulder articular cartilages. It is believed that the kangaroo shoulder joint is anatomically and biomechanically similar to human shoulder joint and it is easy to get in Australia. Therefore, the kangaroo humeral head cartilage was used as the suitable tissue for th...

Trabecular bone is a crucial and unique load-bearing tissue in the skeleton found near the ends of long bones and in the vertebral bodies. Trabecular bone has the ability to rapidly adapt to the mechanical loading environment by optimizing its mass and structure in order to bear high loads with as little bone tissue as possible, allowing bones to remain strong while minimizing their weight. Mea...

Linear and depressed skull fractures are frequent mechanisms of head injury and are often associated with traumatic brain injury. Accurate knowledge and understanding of the fracture of cranial bone can provide insight into the prevention of skull fracture injuries and associated lesions of soft neural tissue and help aid the design of energy absorbing head protection systems. Cranial bone is a...

Finite element (FE) models of long bones are widely used to analyze implant designs. Experimental validation has been used to examine the accuracy of FE models of cadaveric femurs; however, although convergence tests have been carried out, no FE models of an intact and implanted human cadaveric tibia have been validated using a range of experimental loading conditions. The aim of the current st...

863-Pos Board B632 Hydrogen Bond Strength Modulates the Mechanical Strength of FerricThiolate Bonds in Rubredoxin Peng Zheng, Shin-ichi J. Takayama, A Grant Mauk, Hongbin Li. University of British Columbia, Vancouver, BC, Canada. It has long been recognized that hydrogen bonds formed by protein backbone amides with cysteinyl Sulfur atoms play important roles in modulating the functional and str...

The paper introduces a new methodology with a distributed triangle transducer for the strongly coupled simulation of micro electro mechanical systems (MEMS) in ANSYS Finite Element (FE) program.

B4C and its composites with TiB2 as second phase continues to be extensively used as the preferred ceramic material in military applications as armor systems for absorbing and dissipating kinetic energy from high velocity projectiles. It also exhibits a high melting point (2427 °C), and high neutron absorption cross section. Pressureless sintering of the B 4C-nanoTiB2 nanocomposite using small ...
