Analysis of the variation of the magnetic flux around rectangular and triangular defects in ferromagnetic plates. Acta univ [online]. 2020, vol.30, e2336.  Epub 22-Oct-2020.

This article, framed within the context of the project called Development of an expert system for the modelling and monitoring of surface cracks (triangular and rectangular type) in ferromagnetic pipes using the magnetic memory method, presents the analysis of the variation of the magnetic flux around rectangular and triangular defects in ferromagnetic plates. This analysis uses a methodology with an exploratory study of numerical models based on existing analytical models. The obtained numerical models will serve as a basis when comparing them with experimental results to quantify the magnitude of the defects. The results determined, through data analysis, that it is possible to detect and classify the size and shape of rectangular and triangular surface defects with a high degree of certainty and high levels of reliability using the tangential and normal components of these defects.

Palabras llave : Magnetic memory method; geometric defects; magnetic field strength.
