The mechanical response of magnesium alloy AZ31B is addressed thanks to four-point bending tests. These alloys are known have an asymmetrical behavior in tension-compression. test is, therefore, a good candidate analyze this effect because it combines the two solicitations. Digital image correlation used measure evolution strain fields during test. Measurements shift neutral line (zero strain) ...

This study examines the behavior of circular concretes externally confined by green sustainable WHBR FRP containing water hyacinth fiber ropes and bio-resin. principally purposes to discover axial stress-strain relationship FRP-confined concrete. A total 10 with a dimension 150×300 mm were cast, strengthened one four layers FRP, tested under compression. The stress deformability observed be inc...

Self Compacting Concrete offers many advantages over conventional concrete. It is mainly used when a great fluidity is required (For example sections with high percentage of reinforcement). Self Compacting Concrete has excellent applicability for elements with complicated shapes and congested reinforcement. An experimental study was made on cylinders and specimens with square sections confined ...

In this study, we compare the behavior of confined compression-tested concrete test pieces and short beams subjected to three-point flexural strength testing when they are reinforced with high-modulus, high-strength carbon fibers polymers (CFRP). The fabrics used have roughly same mechanical capacity but very different rigidities. As such, results make it possible obtain influence rigidity CFRP...

The importance of Lithium-ion batteries continues to grow with the introduction of more electronic devices, electric cars, and energy storage. Yet the optimization approach taken by the manufacturers and system designers is one of test and build, an approach that nearly every other industry has long abandoned. A computational model is required to reduce the expensive build-test cycle and allow ...

Sputtering was utilized to deposit polycrystalline Cu and CrN films sequentially onto Si(100) substrates, forming specimen assemblies in which predominantly ⟨111⟩ oriented Cu thin films of varying thicknesses were confined between Si and CrN. Cylindrical micro-pillars of CrN/Cu/Si(100)were fabricated through focused ion beammilling,with the interfaces either normal to the axial direction or at ...

The biphasic poroviscoelastic (BPVE) model was curve fit to the simultaneous relaxation of reaction force and lateral displacement exhibited by articular cartilage in unconfined compression (n=18). Model predictions were also made for the relaxation observed in reaction force during indentation with a porous plane-ended metal indenter (n=4), indentation with a nonporous plane ended metal indent...

Hyaff 11 R , a material derived from hyaluronic acid with interesting applications as a scaffold for tissue engineering, is made porous by salt leaching and mechanically tested in simple tension and confined compression. The tests revealed a different behavior in tension and compression, a feature common to other foamed materials. The difference between the behavior in tension and compression i...
