MAGNETIC CIRCUIT DESIGN

SECTION 1: EXPLANATION

Most permanent magnets have a direction of anisotropy, where the magnetic domains are forced into a single direction during the production of the magnetic material. The magnet must then be magnetized in the direction of anisotropy, but being one-dimensional does not mean that the location of magnetic North has…

Magnet Quenched Powder

HSMAG magnetic powders are based upon Nd-Fe-B alloy compositions that are quickly solidified from their molten state at high cooling rates. This rapid solidification results in a material that has a precise grain structure. Due to the small grain size, these materials are magnetically isotropic. Unlike the very fine, anisotropic powders that are used to manufacture sintered…

The aim of this book, which consists of four chapters, is to study two dimensional generalized thermoelastic problems for rotating functionally graded anisotropic plates (FGAPs). A dual-reciprocity boundary element method (DRBEM) is implemented for solving the problems. The accuracy of the proposed method was examined and confirmed by comparing the obtained results with those known previously. These problems are solved under special conditions of the governing equations of generalized thermo-elasticity. This book has a lot of applications in many engineering fields such as modern aeronautics, astronautics, earthquake engineering, soil dynamics, mining engineering, nuclear reactor design, high energy particle accelerators, geothermal engineering, geophysics, plasma physics etc. The results of this thesis show the difference between the four theories of thermo-elasticity Green and Lindsay (G-L) theory, Lord and Shulman (L-S) theory, classical coupled theory of thermo-elasticity (CCTE) and classical uncoupled theory of thermo-elasticity (CUTE) in rotating FGAPs. It can be seen in the figures of this book that the dual reciprocity boundary element method (DRBEM) results are in excellent agreement with the finite element method (FEM) results.

In chapter one, a computerized boundary element model was implemented for solving the two-dimensional problem of the Green and Lindsay (G-L) theory of thermo-elasticity in functionally graded anisotropic (FGA) rotating plates. The accuracy of the proposed dual reciprocity boundary element method (DRBEM) was examined and confirmed by comparing the DRBEM obtained results of the temperature and displacements distributions with the FEM results known previously.

In chapter two, a computerized boundary element model was implemented for solving the two-dimensional problem of the Lord and Shulman (L-S) theory of thermo-elasticity in FGA rotating plates. The accuracy of the proposed method was examined and confirmed by comparing the DRBEM obtained results of the temperature and displacements distributions with the FEM results known previously.

In chapter three, a computerized boundary element model was implemented for solving the two-dimensional problem of the classical coupled theory of thermo-elasticity (CCTE) in FGA rotating plates. The accuracy of the proposed method was examined and confirmed by comparing the DRBEM obtained results of the temperature and displacements distributions with the FEM results known previously.

In chapter four, a computerized boundary element model was implemented for solving the two-dimensional problem of the classical uncoupled theory of thermo-elasticity (CUTE) in FGA rotating plates. The accuracy of the proposed method was examined and confirmed by comparing the DRBEM obtained results of the temperature and displacements distributions with the FEM results known previously.

Magnetic Anisotropy is the capacity of a magnet to maximize its magnetic orientation in the direction of its poles, and it is similar to general anisotropy of other material characteristics.

Strong permanent magnets – especially sintered Neodymium magnets- have had their magnetic domains oriented in the direction of the easy axis to maximize their strength.

Anisotropy is the property of any…
