Hybrid structures are important for the automotive and aeronautical industry as they have potential to reduce vehicle or aircraft weight improve fuel efficiency. Continuous ultrasonic metal welding is a promising technique hydraulic applications in realise tubular metal/fiber reinforced polymer (FRP) hybrids. Fluid proof connections between dissimilar components can be joined by continuous seam...

in this study, in order to investigate the effect of increasing the manganese content on microstructure and mechanical properties of high manganese austenitic steels, three alloys with successive increases in weight percentages of manganese (7.55, 13.1, and 16.5) and carbon (0.8 and 1.2) were cast in the presence of a constant amount of chromium (1.5 wt.%) and silica (0.6 wt.%). the samples exp...

Due to significant environmental advantages, biocomposites have recently received increasing attention. In the present research, strength of hat-shaped coir fiber biocomposites tubes reinforced with nano powder was evaluated experimentally under 3-point bending tests. The tubes were manufactured using hand lay-up technique and based on Taguchi design of experiment. The effects of different para...

The dynamical response of magnetic flux tubes due to local transverse periodic perturbations is investigated by numericalmeans.Our aimwas to check the applicability of the thin flux tube approximation for vertically oriented flux tubes with moderate magnetic field strength (plasma β = 1) and diameters 100 km, 50 km and 25 km immersed in an otherwise homogeneous nonmagnetic environment. All tube...

I present results from a set of 3D spherical-shell MHD simulations of the buoyant rise of active region flux tubes in the solar interior which put new constraints on the initial twist of the subsurface tubes in order for them to emerge with tilt angles consistent with the observed Joy’s law for the mean tilt of solar active regions. Due to the asymmetric stretching of the Ω-shaped tube by the C...

A common mechanism for intracellular transport is the controlled shape transformation, also known as pearling, of membrane tubes. Exploring how tube pearling takes place is thus of quite importance to not only understand the bio-functions of tubes, but also promote their potential biomedical applications. While the pearling mechanism of one single tube is well understood, both the pathway and t...

Metallic tubes, under axial loading, are frequently preferred in many different industries due to their high energy absorption efficiency. The studies increase the capacity (EAC) of these structures still up date. In this study, deformation behavior and EAC regionally pre-deformed identical aluminum steel tubes loading were investigated experimentally. Regional strength was obtained by radial w...

This paper presents a study about the bond of high strength concrete with high strength steel. Fourteen pull out tests were carried out to determine the bond. The concrete strength was about 70 MPa and the steel was a 500 MPa grade. Bar diameters used were 12, 16, 20, 25, 28, 32 and 36 mm. In order to investigate the effect of cover, each test was done twice, once in a 240 mm diameter concrete ...
