In this experimental work, AISI 304 was welded via metal inert gas (MIG) welding process with Argon (Ar) as shielding gas. In the present study, AISI 304 was subjected to different heat input using a standard 308L electrode. Weld quality i.e. ultimate tensile strength, toughness, microhardness, and microstructure of AISI 304 were examined. Microstructures of welded joints were studied using sca...

electromagnetic forming is a high energy rate forming process in which an electromagnetic lorentz body force is used for deformation of products.  in this article, electromagnetic forming process was simulated for the assembly of parts as an innovative method.  the effect of important process parameters such as discharge energy, radius and width of rectangular groove on the strength of the asse...

resin- dentin interface hydrolysis is one of the greatest problems in restorative dentistry, because of collagenolytic and proteolytic activity of dentin enzymes. the aim of this study was to compare the effect of chx 2% and naocl 5% as rewetting agent on resin-dentin micro tensile bond strength.methods: 45 extracted, human caries-free third molar teeth were collected. after exposing of superfi...

The screening efficiency of a metal-ferroelectric interface plays a critical role in determining the polarization stability and hence the functional properties of ferroelectric thin films. Imperfect screening leads to strong depolarization fields that reduce the spontaneous polarization or drive the formation of ferroelectric domains. We demonstrate that by modifying the screening at the metal-...

Density functional theory-based ab initio simulations were performed to investigate the bond strength of an Fe(001)/Al(001) coherent interface, its atomic configuration, oxidation at and mechanical deformation along lateral direction interface. The bcc-type interface exhibited highest in terms work separation, but decreased significantly when oxygen was introduced. fracture bare initiated Al ma...

We study the dynamics of an exactly solvable lattice model for inhomogeneous interface growth. The interface grows deterministically with constant velocity except along a defect line where the growth process is random. We obtain exact expressions for the average height and height fluctuations as functions of space and time for an initially flat interface. For a given defect strength there is a ...

In this paper the e€ect of ®nite interface strength, and possible debonding, on the macroscopic response of a sample of ®ber-reinforced composite material is computationally investigated via the ®nite element method. The sample consists of several ®bers embedded in a homogeneous matrix, aligned in the longitudinal direction, and randomly distributed in the transverse direction. Plane strain con...

AIM The aim of this study was to evaluate the bond strength and crown-repair material interface of polycarbonate crown repaired using flowable resin composite and hybrid resin composite following two different surface preparations. METHODS AND MATERIALS The facial surfaces of fifty-two polycarbonate crowns were flattened and roughened. Specimens were then divided into four test groups. A bond...
