Machining in the scale of nanometer and investigating its behavior is premier in the field of machining. Molecular dynamics is a new robust tool to investigate controlling mechanisms in atomic scales, complex dislocation, and ...

In this paper, the effects of two parameters named width of the roller and exerted force on it in direct and indirect rolling, on residual stresses in Friction Stir Welding (FSW) process of SU304 steel have been studied. ...

Ensuring the safety of passengers as much as possible is essential in automobile and airplane accidents. In this study, an open-cell aluminum foam was introduced as an energy absorber. Analytical equations of absorbed ...

In this paper, the static response of functionally graded piezoelectric plates under mechanical, electrical, and thermal loads is studied using a meshless method. The Radial Point Interpolation Method (RPIM) is used to ...

In this research, Constraint Groove Pressing (CGP) process, which is one of the most important and effective methods of severe plastic deformation processes has been studied. Ultrasonic assisted CGP (UCGP) process has been ...

In this article, the friction stir welding of dissimilar AA6061-T6/AA7075-T6 aluminum alloys was studied experimentally. The joining process was implemented with and without the addition of the TiO2 nanoparticles. To ...

In the current study, magnesium-matrix AZ31/ 1.5 vol.% (TiO2)p nanocomposites manufactured using stir casting underwent extrusion process. The as-cast ingots were extruded, then processed by multidirectional forging (MDF) ...

Continuous investigation and measurement of pore water pressure and arching depression play an important role in detecting the occurrence of hydraulic failure in earth dams. Increasing the pore water pressure during the ...

Twist extrusion is a novel method for severe plastic deformation of materials. Severe plastic deformation in metals creates small and uniform grain size and therefore increases their mechanical strength. In this study, the ...

Nowadays, composites have great applications in mechanical structures due to their proper ratio of the strength to the weight. Such application includes automotive and aerospace industries. These components may be affected ...

The effect of pre-compaction on mechanical properties of Mg/SiC nanocomposites prepared through dynamic compaction was investigated. The dynamic compactions were carried out at two different loading rates using Drop ...

Friction stir processing (FSP) in different pass number, accordingly one and four, was performed to AZ31 magnesium alloy. Optical and scanning electron microscopy (SEM) were used to investigate the effect of FSP and its pass ...
