A Probabilistic Model for Simulating Magnetoacoustic Emission Responses in Ferromagnets
نویسنده
چکیده
Magnetoacoustic emission (MAE) is a phenomenon where acoustic noise is generated due to the motion of non-180 ° magnetic domain walls in a ferromagnet with non-zero magnetostrictive constants. MAE has been studied extensively for many years [1-5] and has even been applied as an NDE tool for characterizing the heat treatment of high-yield low carbon steels [6-8]. A complete theory which fully accounts for the magnetoacoustic response, however, has not yet emerged.

Self-organized Criticality and Phase Problem in Magnetoaocustic Emission Burst in Ferromagnets
Two types of ferromagnets, pure iron and steel with varying geometry and microstructural properties, were prepared for the present study of magnetoacoustic emission (MAE). The purpose was to separate the effects of structural property variations from changes caused by differences in the sample geometry. The position and shape of the leading MAE sub-burst and its variation among the samples are ...

In this paper an epistemological model of learning fields of probabilistic events is formalized. It is used to explain resource allocation governed by pervasive complementarities as the sign of unity of knowledge. Such an episteme is induced epistemologically into interacting, integrating and evolutionary variables representing the problem at hand. The end result is the formalization of a p...

متن کاملSlow magnetoacoustic waves in coronal loops
A theoretical model interpreting propagating disturbances of EUV emission intensity, recently observed in coronal loops, is constructed in terms of slow magnetoacoustic waves. The model is one-dimensional and incorporates effects of nonlinearity, dissipation due to finite viscosity and thermal conduction, and gravitational stratification of plasma in the loop. It has been found that, for the ob...
متن کاملCharacterization of Magnetoacoustic Emission Related to Structural Properties of Ferromagnets
An extensive study of magnetoacoustic emission (MAE) properties has been performed over the past several years[1, 2]. As a result, the dependence of the spectral characteristics of MAE on certain microstructural variations and uniaxially applied stress in a particular type of low carbon steel are now well known. The embrittlement-causing concentration of certain atomic species, e. g., tin, sulp...
