Forced convection boundary layer magnetohydrodynamic flow of a nanofluid over a permeable stretching plate is studied in this paper. The effects of suction-injection and viscous dissipation are taken into account. The nanofluid model includes Brownian motion and thermophoresis effects. The governing momentum, energy, and nanofluid solid volume fraction equations are solved numerically using an ...

We investigate the transient viscoelastic behavior of weakly strain-hardening fluids in filament stretching devices during uniaxial elongation and following the cessation of stretching. The numerical results are compared with experimental observations on a concentrated shear-thinning polystyrene solution which is well characterized by a multi-mode Giesekus model. The finite element computations...

Plate-based lattices are predicted to reach theoretical Hashin–Shtrikman and Suquet upper bounds on stiffness strength. However, simultaneously attaining high energy absorption in these plate-lattices still remains elusive, which is critical for many structural applications such as shock wave absorber protective devices. In this work, we present bi-material isotropic cubic + octet sandwich comp...

Abstract During the immersion quenching process, severe temperature changes and significant differences between core superficial area can give rise to high residual stresses within aluminum alloy thick plate cause subsequent machining distortion of thin-walled part. Reducing stress effectively minimize in In this research, ABAQUS software was adopted simulate internal fields plates Al7055 durin...

The present article investigated the unsteady flow of a nanofluid past an isothermal magnetized plate emanating from moving slot. This unique form boundary layer is analogous to stretching/shrinking sheet problems subject direction motion Governing partial differential equation can be reduced into similar using Blasius–Rayleigh–Stokes variable. consequences movable slot and magnetic field on he...

An analytic technique, namely, the homotopy analysis method, is applied to give series solution of the unsteady boundary-layer flows over an impermeable stretching plate. Different from all previous perturbation solutions, our series solutions are convergent in the whole time region 0 ≤ τ < +∞. To the best of our knowledge, such kind of series solution has never been reported for this problem. ...

[1] We give an explanation for the polarity, localization, shape, size, and initiation of subduction zones on Earth. By considering a soft, thin, curved lithospheric cap with either elastic or viscous rheology supported by a thick, nearly incompressible mantle, we find two different characteristic subduction geometries arise depending on boundary conditions: (1) plate boundaries where subductio...

Progressive radial cracking of a clamped plate subjected to crack-face closure is studied. The material behavior is assumed to be elastic-brittle. The cracks are assumed to be relatively long in the sense that the three-dimensional contact problem can be described via a statically equivalent two-dimensional idealization. The number of cracks is supposed large enough to permit a quasi-continuum ...

Stretching is a common activity used by athletes, older adults, rehabilitation patients, and anyone participating in a fitness program. While the benefits of stretching are known, controversy remains about the best type of stretching for a particular goal or outcome. The purpose of this clinical commentary is to discuss the current concepts of muscle stretching interventions and summarize the e...
