Needle bevel geometry influences the flexural deflection magnitude in ultrasound-enhanced fine-needle biopsy [PDF]
arXiv, 2022 It has been recently demonstrated that use of ultrasound increases the tissue yield in ultrasound-enhanced fine-needle aspiration biopsy (USeFNAB) as compared to conventional fine-needle aspiration biopsy (FNAB). To date, the association between bevel geometry and needle tip action has not been widely explored.

Bending of chiral fractal lattice metamaterials [PDF]
arXiv, 2022 We describe the out-of-plane bending of chiral fractal lattices metamaterials by using a combination of theoretical models, full-scale finite elements and experimental tests representing the flexural behaviour of metamaterial beams under three-point bending. Good agreement is observed between the three sets of results. Parametric analyses show a linear

Tunable cylindrical shell as an element in acoustic metamaterial [PDF]
J. Acoust. Soc. Am., 136(4), 1601-1609, 2014, 2014 Elastic cylindrical shells are fitted with an internal mechanism which is optimized so that, in the quasi-static regime, the combined system exhibits prescribed effective acoustic properties. The mechanism consists of a central mass supported by an axisymmetric distribution of elastic stiffeners.

Physical and mechanical properties of composites produced from recycled polypropylene and cardboard-polyethylene-aluminium mixture [PDF]
Tribology and MaterialsPlastic-containing waste causes significant environmental pollution because it remains in nature for a long time without degrading. This waste includes polyolefin-based containers, polyethylene terephthalate water bottles and cardboard-polyethylene ...

Experimental analysis and finite element modeling of the piston-on-three balls testing of Y-TZP ceramic [PDF]
Cerâmica, 2019 The objectives of this study were to characterize and evaluate the physical and mechanical properties of an experimental zirconia for dental application and compare the biaxial flexural strength results with the finite element simulation (FEM).

Energy storage in structural composites by introducing CNT fiber/polymer electrolyte interleaves [PDF]
Scientific Reports; 2018, 8, 3407;, 2018 This work presents a method to produce structural composites capable of energy storage. They are produced by integrating thin sandwich structures of CNT fiber veils and an ionic liquid-based polymer electrolyte between carbon fiber plies, followed by infusion and curing of an epoxy resin.
