Abstract
UN METODO PARA LA DETERMINACION DEL DAÑO POR FLUENCIA EN UNA PIEZA DE TRABAJO FERROMAGNETICA. LA COMPROBACION NO ES DESTRUCTIVA RAPIDA DE UNA PIEZA DE TRABAJO FERROMAGNETICA PARA DETERMINAR LA DETERIORACION POR FLUENCIA SE EFECTUA SITUANDO UNA BOBINA DE CORRIENTES DE FOUCAULT (1) EN UNA POSICION ADYACENTE A LA PIEZA DE TRABAJO (3), HACIENDO PASAR UNA CORRIENTE ALTERNA A TRAVES DE LA BOBINA, MIDIENDO LA RESPUESTA DE CORRIENTES DE FOUCAULT BAJO LA INFLUENCIA DE LA PIEZA DE TRABAJO, Y COMPARANDO LA MEDICION DE CORRIENTE CON UNA CORRIENTE CALIBRADA PARA CORRESPONDER CON UNA DETERIORACION POR FLUENCIA CONOCIDA DEL MATERIAL FERROMAGNETICO DADO. SE GENERAN CORRELACIONES DE LA RESPUESTA DE CORRIENTES DE FOUCAULT CON LA VELOCIDAD DE FLUENCIA Y EL TIEMPO QUE TRANSCURRE HASTA EL FALLO, A PARTIR DE PRUEBAS DE ROTURA POR FLUENCIA EFECTUADAS EN ESPECIMENES DEL MATERIAL SOMETIDO A DIVERSAS CONDICIONES DE TIEMPO, TEMPERATURA Y ESFUERZO.
