In this scheme, permanent magnet strength is controlled depending on magnetization direction, and consequently the final permanent magnet design converges into permanent magnet segments having target discrete directions.
In this scheme, the permanent magnet strength and permeability are controlled by density design variables, and permanent magnet magnetization directions are controlled by angle design variables.
In addition, it is even possible to render θB=0 via proper manipulation of the permanent polarization strength and its orientation, as well as the magnetic permeability.
Based on isoparametric shape functions used in the finite element analysis, the permanent magnet strength and magnetization directions in a Halbach array are simultaneously optimized for a given design goal.
Specifically, the laser power was about 63 mW, the light spot diameter was 1.2 mm and the permanent magnet strength was 0.1 T. Besides, we choose x, y and z to be along [1 1 ¯ 0], [110] and [001] crystallographic directions, respectively.
In this study, the volumetric properties, Marshall stabilities, the indirect tensile stiffness moduli, and the fatigue and permanent deformation strengths of hot mix asphalts prepared with the same performance grade binders in accordance with Superpave method at optimum binder contents were comparatively investigated.
It is found that the resilient modulus, permanent deformation, shear strength, and erosion are key factors.
Properties adversely affected by non-compatible rubber blends include tensile strength, permanent set, low temperature behavior and covulcanizability.
The viscoelastic, strength, permanent deformation and fatigue characteristics of the neat and modified mixtures were evaluated under indirect tension mode.
Curie temperature measurement is accomplished in some DSC-TGA geometries by the placement of a high strength permanent magnet just outside the temperature controlled chamber [10, 11].
