Extrusion-based 3D concrete printing is analogous to fused deposition modeling method, which extrudes cementitious materials from a nozzle to build a complex concrete structure layer-by-layer without the use of expensive formwork.

Asymmetric flexural wave transmission based on dual-layer elastic gradient metasurfaces
Applied Physics Letters, 2018Traditional asymmetric transmission of elastic waves is mostly based on mode conversion, which presents a real challenge to get pure-mode elastic waves.

FRP jacketed concrete under flexure and combined flexure-compression
Construction and Building Materials, 1995Abstract In this investigation experimental data were developed to evaluate the behaviour of concrete members laterally confined with fibre-reinforced plastic ( frp ) composites. Specimens were loaded quasi-statically under cyclic flexure with and without axial compression.

Deflecting flexural wave with high transmission by using pillared elastic metasurface
Smart materials and structures (Print), 2018This paper proposes an innovative and simple elastic metasurface, which is one kind of ultrathin metamaterial, to abnormally deflect normally and obliquely incident flexural waves. In particular, negative refraction of flexural wave is also realized. The

Abstract T he paper deals with the plastic flexure and torsion of prismatic beams loaded by terminal bending and twisting moments which, acting together, cause full plastic flow. The material is assumed to behave according to the Tresca-Levy-Mises hypotheses, and in nonhardening and rigid plastic.

The deformation of the earth's crust under superposed loads is considered as a problem in structural mechanics. The crust is treated as a uniform, elastic, thin, spherical shell, and the mantle is treated as an enclosed viscous liquid. Equations relating loading and crustal response are developed.

Clinical experiences with the splenic flexure syndrome and the hepatic flexure syndrome
The American Journal of Digestive Diseases, 1955Excess gas in the hepatic flexure or splenic flexure of the colon, although in itself not unusual nor necessarily significant, may at times be the explanation for symptoms suggesting cardiac, stomach, gall bladder, kidney or pulmonary disease. The concept of the hepatic and splenic flexure syndromes has proved to be of positive clinical value.

Influence of infill properties on flexural rigidity of 3D-printed structural members
Virtual and Physical Prototyping, 2018This paper characterises the flexural properties of relatively slender structural members (beams) manufactured using a FDM-based 3D printer. The primary goal is to assess the influence of infill properties on flexural rigidity through a parametric ...

Lattice flexures: Geometries for stiffness reduction of blade flexures
Precision Engineering, 2016Abstract Reducing the motion-direction stiffness of compliant mechanisms reduces their actuation effort and simplifies associated static balancing mechanisms. This work introduces a flexure type called lattice flexures and evaluates some of their fundamental properties.

An effective baffle must have a high insertion loss which is usually measured with normally incident plane sound waves. In some applications the following question arises. Is a baffle which has a high acoustic insertion loss also effective when used in other situations where acoustic insertion loss is not the direct requirement?
