Introduction Compared to conventional polishing technologies, MRF is a deterministic, sub-aperture finishing process with system stability, high material removal rates and a shear mode of material removal that makes it uniquely well-adapted to a variety of optical and industrial applications [[] M.

Introduction Nowadays, materials consisting piezoelectric and piezomagnetic components have found increasing applications in engineering structures, particularly in so-called smart materials/intelligent structures.
Yet magnetoelectroelastic coupling has both theoretical and practical significance in solid-state physics and materials science.
Reference [13] considered the magnetoelastic problem of straight cracks lying along the interface of two dissimilar soft ferromagnetic materials subjected to remote uniform magnetic induction.
Recently, [15] studied magnetoelectroelastic materials involving geometrical disturbance, such as a cavity or a crack.

K and n are two material coefficients characterizing the viscous effect of a hardened material.
For this reason, many hardened materials become exponentially weaker at higher temperatures.
Our results show that, taking Schmid stress as driving force, the sole cause for plastic deformation as in Eq. 1 isnot appropriate for materials with complex microstructure and cannot be applied at high temperature moderate stress regimes.

We identified that the Online Learning Experience, or the technological resources, tools, and materials available, would achieve the Collaborative Learning Experience, or the activities and interactions.
These approaches placed learners/users as self-determined learners or ‘agents of change’, promoting autonomy to explore and interpret the resources, materials and the online environment and build their learning pathway.

Thus, separation of these bundles and dispersion and alignment of the individual CNT are crucial steps for several applications, hence becoming an important challenge in composite materials preparation.
In order to produce conductive composite materials with functionalized CNT, it is important to keep as much as possible the structural integrity of CNT and their electrical properties.
