One of the important characteristics of magnetic materials is the measurement of magnetic characteristics through Superconducting Quantum Interference Device (SQUID) especially magnetization temperature dependence M(T)ZFC and MTFC measurement.
For ferromagnetic or ferrimagnetic materials, with small enough nanoparticles their magnetization becomes thermally fluctuated.
In the single domain structure, superparamagnetic materials can fluctuate randomly by thermal fluctuation at high enough temperatures just as an atom spin in paramagnetic materials.

Nonlinear Finite element analysis of joint model The constitutive of materials In the finite element analysis, the steel is assumed to be isotropic material.
The elastic modulus, yield strength of steel is determined by the material performance test.
The test specimens due to the existence of bias weld defects, brittle material, processing model size, initial defect.

Direct manufacturing cost includes material cost, energy cost and salary cost.
Then, purchase cost () can be expressed as: (3) 3) Relation model between purchase cost and reliability Since direct manufacturing cost (planning, design, test and raw materials) increases as reliability improves, they are closely related with reliability and can be expressed by the function of reliability.
However, limited by technologies and materials, the developed EMU may achieve a maximum reliability () instead of absolute reliability.
