Single point incremental sheet metal forming is a sheet metal forming process that forms products without the complex dies and tools with low cost. In this study, the incremental sheet metal forming process has been experimentally investigated on the explosively-welded Al/Cu bimetal sheets. Also, the effects of process parameters, such as arrangement of layer`s bimetal, tool diameter and tool p...

The healing of graphene grown from a metallic substrate is investigated using tight-binding Monte Carlo simulations. At temperatures (ranging from 1000 to 2500 K), an isolated graphene sheet can anneal a large number of defects suggesting that their healings are thermally activated. We show that in the presence of a nickel substrate we obtain a perfect graphene layer. The nickel-carbon chemical...

Study of photon decay rate is essential to various optical devices, where graphene is an emerging building block due to its electrical tunability. In this paper, we study photon decay rate of a quantum emitter near a metallic split-ring resonator, which is embedded in a multilayered substrate incorporating a graphene layer. Analyzing photon decay rate in such a complex multilayered system is no...

Nowadays, application of implants as a new method for replacing extracted teeth have been improved. So, many researches have been performed for improving the characteristics of implants. The aim of this study was to design and produce a desired coating in order to obtaining two goals including improvement of the corrosion behavior of metallic endodontic implant and the bone osseointegration sim...

One major problem of the conventional solar cells is low conversion efficiency. In this work, we have proposed a new design including hemisphere texturing on top and metallic plasmonic nanostructure under the silicon layer to enhance the optical absorption inside the photosensitive layer.    The finite-difference time-domain (FDTD) method has been used to investigate the interaction of light wi...

Abstract Steel sheet pile walls are being widely used in civil engineering projects for support systems. Soil is not uniform in depth, sometimes may be exit loose or soft soil layer in various depth. This issue can cause different effects on ground surface displacements, forces and moments acting on sheet piles and struts during excavation procedure, compared with status that soil is uniform...

This paper investigates the convective heat and mass transfer in nanofluid flow through a porous media due to a stretching sheet subjected to magnetic field, viscous dissipation, chemical reaction and Soret effects. Two types of nanofluids, namely Cu-water and Ag-water were studied. The governing boundary layer equations are formulated and reduced to a set of ordinary differential equations usi...

‎the problem of two-phase mhd boundary layer flow, heat and mass transfer over a stretching sheet with fluid-particle suspension and thermal radiation has been studied. the effect of mass transfer in dusty fluid over a stretching sheet is considered for the first time. the governing equations are reduced to a set of non-linear ordinary differential equations under suitable similarity transforma...

However, problems such as osteoporosis due to high elasticity of metals relative to bones, and local infections and systemic problems caused by releasing metallic ions have motivated research on replacing metallic screws with non metallic ones. In this study, the composite containing poly-l-lactic acid and bioactive glass fibers were considered for the design of the screw using ABAQUS software ...
