In this research, static stresses analysis of boron nitride nano - tube reinforced composite (BNNTRC) cylinder made of poly - vinylidene fluoride (PVDF) subjected to non - axisymmetric thermo - mechanical loads and applied voltage is developed. The surrounded elastic medium is modelled by Pasternak foundation. Composite structure is modeled based on piezoelectric fiber reinforced composite (PFR...

Abstract Additive manufacturing (AM) techniques represent a real challenge to manufacture novel composites with coupled multifunctional properties. This work focuses on the mechanical, electrical and thermal behaviours of 3D printed polymeric polylactic acid (PLA) filled carbon black (CB) conductive particles . The incorporation within polymer matrix allows for programmable conduction paths via...

In this work a mathematical model is developed for measuring orientation of red blood cells in magnetic field and governing the bio-magnetic fluid flow is presented for the viscous, two-dimensional, incompressible and laminar time dependent heat transfer flow is considered. Expressions describing the variation of the saturation magnetization of the fluid with temperature or the magnetic field i...

Magnetic shape memory alloys display magnetic-field-induced strain (MFIS) of up to 10% as single crystals. Polycrystalline materials are much easier to create but display a near-zero MFIS because twinning of neighboring grains introduces strain incompatibility, leading to high internal stresses. Pores reduce these incompatibilities between grains and thus increase the MFIS of polycrystalline Ni...

This paper presents the surface piezomagnetoelasticity theory for size-dependent buckling analysis of an embedded piezoelectric/magnetostrictive nanobeam (PMNB). It is assumed that the subjected forces from the surrounding medium contain both normal and shear components. Therefore, the surrounded elastic foundation is modeled by Pasternak foundation. The nonlocal piezomagnetoelasticity theory i...

The coupled magneto-thermal problem is analyzed, with reference to a particular heating application, by means of an equivalent thermal network, that is based on a first-approximation interpretation of the field equations. The connections between the thermal characteristics and the magnetic ones are taking into account by considering the skin-effect and the dependence of electric conductibility ...

Atomic magnetometers (AM) are finding many applications in biomagnetism, national security, industry, and science. Fiber-coupled (FC) designs promise to make them compact and flexible for operation. Most FC designs are based on a single-beam configuration or electrical heating. Here, we demonstrate a two-beam FC AM with laser heating that has 5 fT/Hz1/2 sensitivity at low frequency (50 Hz), whi...

In this work, the results are presented of a 3D numerical magneto-hydrodynamic (MHD) simulation of direct current (DC) electromagnetic pump for liquid aluminum at large Reynolds number under externally imposed non-uniform magnetic field. The formulation of the magneto hydrodynamic model has been derived from the Reynolds-Averaged NavierStokes equations with standard k-ε turbulence model coupled...
