Compression-compression fatigue testing of metallic-glass foam is performed. A stress-life curve is constructed, which reveals an endurance limit at a fatigue ratio of about 0.1. The origin of fatigue resistance of this foam is identified to be the tendency of intracellular struts to undergo elastic and reversible buckling, while the fatigue process is understood to advance by anelastic strut b...
The present study aims to establish comprehensive test methods to evaluate the mechanical properties of the intravascular coronary stent with a closed cell design. We focused on three important mechanical properties required to the stent, bending flexibility, radial strength, and longitudinal strength. Test apparatuses and testing procedures were then developed for precise evaluation of those p...
INTRODUCTION: Stability of the proximal humeral fracture can be difficult to achieved if osteoporosis or severe loss of bone stock is presented. Recently, locking plate technology has included these fractures, but appears that may not be predictable as hoped. Recent studies have demonstrated the importance of both reduction and mechanical support of the medial column in proximal humerus fractur...
In the present work microstructural evolution of A356 Aluminum alloy using an inclined cooling plate casting process for thixoforming feedstock production is investigated. The resultant microstructure was evaluated and compared with those of the same alloy produced by the conventional casting process, i.e. directly cast in the same mold without using an inclined cooling plate. It was found that...
Introduction The fibula osteocutaneous flap is now commonly used to reconstruct composite mandibular defects. Difficulties in flap execution are invariably related to the dynamic relationship of the bone orientation and the skin paddle inset. Traditional design has been limited to a single-strut bony design in order to restore mandibular continuity, without restoration of mandibular height and ...
Varying degrees of order have been found experimentally for a series of covalent triazine-based frameworks (CTFs) when synthesised under different reaction conditions. Here, we use molecular modelling to discuss the potential origins of this structural order by analysis of the node and strut building blocks. We use a combination of small model structures based on DFT optimised monomer units and...
Abstract This paper presents a relative fuel burn evaluation of the transonic strut-braced-wing configuration for regional aircraft class in comparison to an equivalent conventional tube-and-wing aircraft. is accomplished through multipoint aerodynamic shape optimisation based on Reynolds-averaged Navier-Stokes equations. Aircraft concepts are first developed low-order multidisciplinary design ...
Many materials and structures consist of numerous slender struts or fibers. Due to the manufacturing processes different types growth natural fibers, their mechanical response frequently fluctuates from strut strut, as well locally within each strut. In associated models is often represented by a string beam elements, since use conventional 3D finite elements renders simulations computationally...
Strut-based lattice structures produced by powder bed fusion are prone to characteristic manufacturing defects that alter both their form and surface texture. Most studies in the literature focus on a subset of commonly observed defects, typically radius variation strut waviness; remain relatively unexplored. Furthermore, there remains need for development general finite element modelling frame...
[Purpose] The present study assessed the effects of using an unstable inclined board on the active and passive ankle range of motion in patients with ankle stiffness. [Subjects] The study included 10 young female patients with ankle stiffness. [Methods] The patients were divided into the following two groups: a group that performed ankle dorsiflexion stretching exercises using a wooden inclined...
