Abstract

In this paper, the computation of magnetization of a strand constituted of two superconducting square bars immersed in a uniform magnetic field is studied. The numerical results are obtained from the program developed with the FEM. Bean's critical state model is carried out to characterize the electrical behavior law of superconducting materials. The magnetization cycle, the magnetic field and the current density distributions are presented. The influence of strand length on the electromagnetic coupling phenomena in the superconducting square bars is also considered. The obtained results are in good agreement with the theoretical results. [ABSTRACT FROM AUTHOR]

88. Modeling of Magnetoelastic and Piezoelectric Coupling: Application to SRM Noise Damping.

Abstract

This paper examines a model of magnetomechanical and piezoelectric coupling. This model, based on the association of the magnetoelastic and piezoelectric constitutive laws, is implemented in a transient finite element formulation. The application is the reduction of the noise emitted by switched reluctance machines by means of an active damping. The active elements are piezoelectric actuators placed on the stator, for the purpose of reducing its vibrations. The control is based on a positive position feedback regulation. Thus, an infinite impulse response filter is added to the model in order to control the piezoelectric elements depending on information of the stator vibration. [ABSTRACT FROM AUTHOR]

Abstract

Vibrations in thin structures are often not desired, especially because of their harmful effects on lifespan. The addition of piezoelectric materials with appropriate connections can really be useful to reduce this drawback. To study such a damping effect, numerical modeling is necessary and leads to a coupled problem (between mechanics and electricity). This paper presents a 2-D model of a plate with piezoelectric patches. From the coupled behavior laws and with the use of a variational formulation, a finite element model is developed. After a validation process, the influence of the width of piezoelectric patches on damping is studied. [ABSTRACT FROM AUTHOR]

90. Optimal Design of Magnetostrictive Composites: An Analytical Approach.

Subjects
ASYMPTOTIC homogenization, MAGNETOSTRICTION, MECHANICAL behavior of materials, OPTIMAL designs (Statistics), PHYSICS education
Abstract

Giant magnetostriction materials, such as Terfenol-D, have allowed the development of a new class of actuators and sensors based on magnetoelastic properties. However, their mechanical properties are a limiting factor for some applications. Composites, made of Terfenol-D particles in a matrix, can bypass these limitations, improving the overall mechanical properties while maintaining the magnetostriction effect. But, to optimize the design of magnetostrictive composites, advanced modeling tools are needed. This paper proposes a homogenization model based on inclusion problems. It compares modeling results to experimental data from the literature, and it illustrates the use of the model as a tool for optimal design. [ABSTRACT FROM AUTHOR]

Abstract

In the large hadron collider main magnets, persistent currents in the superconducting filaments determine the quality of the magnetic field at an injection field. It is thus necessary to examine the magnetization of the superconducting filaments during production of the cable strands. The prediction of the magnetization can be based on numerical solutions obtained by using the finite-element method. We have computed the magnetization curves of coupled and noncoupled superconducting filaments in two dimensions. In addition, we have taken into account the dependence of the current density according to the magnetic field. [ABSTRACT FROM AUTHOR]
