Abstract:
Abstract Archery is a tradition, a style of martial arts and a competitive sport, while at the same time being an art form. The equipment consists of a bow and arrows. The deflection of the arrow is a very important characteristic, one which has a decisive influence on how and if the arrow reaches the target. This has a tremendous impact on the performance of the archer in both competition and archery demonstrations. The quantification and measurement of arrow deflection is equally important to both manufacturers and archers. It is affected by the arrow’s static bending. In this paper the bend

Abstract:
The paper reports on two specific research activities devoted on the one hand to detailed finite element simulations of glued timber beams with emphases on random nature of the modulus of elasticity and, on the other hand, to destructive testing of a set four glued timber beams having structural dimensions. While the stochastic simulations were founded on the knowledge of probability density distributions of the modulus of elasticity acquired from non-destructive testing of local moduli from 3600 regularly spaced indentation measurements, the destructive testing of beams in four-point bending

Wood is increasingly difficult to obtain due to the use of excess wood. Many efforts were made to replace wood, one of which was composite material. This study aims to determine the most optimal bending strength with the influence of variations in volume fractions and fiber orientation in hybrid composites with luffa fibers and hyacinth fibers. In making composites using the hand lay-up method with alaklization treatment on gambas and hyacinth fibers using 5% NaOH which is varied with the volume fraction used in this study with the ratio of resin: hyacinth: gambas is (60%:20% :20%),(70%:15%:15

Abstract:
A requirement of flexible electronic devices is that they maintain their electrical performance during and after repetitive mechanical deformation. Accordingly, in this study, a universal test apparatus is developed for in-situ electrical conductivity measurements for flexible electrodes that are capable of applying various mechanical deformations such as bending, twisting, shearing, sliding, stretching, and complex modes consisting of two simultaneous deformations. A novel method of deforming the specimen in an arc to induce uniform bending stress in single and alternating directions is also

SummaryThe biomechanical testing of tubes made of third generation short glass fibre-reinforced (SGFR) material approximating cat femurs was performed in order to determine their suitability as cat femur surrogates for the biomechanical testing of orthopaedic implants. The tubes were tested in compression, three-point bending, notch testing, and screw pullout. Thin walled (B1-tubes) had a 13% lower maximum load to failure, a 19% higher maximum strength and a 13% lower elastic modulus compared to cat femurs tested in compression. B1-tubes maximum load to failure in threepoint bending and screw

This paper explores polycrystalline 3C-silicon carbide (poly-SiC) deposited by LPCVD for fabricating flexible ribbon cable interconnects for micromachined neural probes. While doped silicon is used currently, we hypothesized that poly-SiC will provide enhanced mechanical robustness due to SiC’s superior mechanical properties. Paralleling prior work in silicon, forty-two different designs were fabricated from nitrogen-doped poly-SiC films deposited by LPCVD at 900°C using dichlorosilane and acetylene as precursors. The different designs were then tested in bending and twisting modes. Curved bea

Abstract:
INTRODUCTION: Screw use for SIJ fixation began in the 1980s with the FDA first classifying SIJ fusion devices in 2002. For 40 years, no standardized test method existed. Various methodologies (for bone screw, intramedullary nail, or spinal fusion implants) were modified to accommodate the design and function of sacroiliac devices including ASTM F543’s torsion, pullout, and insertion tests, ASTM F1264’s three- or four-point bending tests, and ASTM F2193’s cantilever bending tests. For many years, SIJ fusion screw indications were limited to fixation of pelvic bones for sacroiliac joint disrupti

Abstract:
In this study, a drop weight testing method was employed to investigate the impact bending behavior of ethylene vinyl acetate (EVA) modified engineered cementitious composite (ECC). The ECC with no EVA was selected as control, and the static and impact bending behavior was compared with the EVA modified ECC. The results showed that the compressive strength of EVA modified ECC decreased by 20%~30% in comparison with control ECC with fly ash substitution ratio variation. The addition of EVA can improve the bending toughness of ECC dramatically under static loading condition. As different from th
