Este análisis utiliza una metodología con un estudio exploratorio de modelos numéricos a partir de modelos analíticos existentes. Los modelos numéricos obtenidos servirán como base al compararlos con resultados experimentales para cuantificar la magnitud de los defectos. Los resultados determinaron, a través del análisis de datos, que es posible detectar y clasificar, con un alto grado de certidumbre y alto nivel de confiabilidad, el tamaño y la forma de los defectos superficiales tipo rectangular y triangular mediante los componentes tangencial y normal de esos defectos.]]></p></abstract>

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.]]></p></abstract>
