Abstract

Método de ensayo del estado de materiales, que comprende las etapas de inyectar una señal de ultrasonidos de entrada xinp(n) con una frecuencia f dada en una muestra de material que va a someterse a ensayo, siendo f inferior o igual a la frecuencia característica del material sometido a ensayo; recibir una señal de salida x(n) tras su paso a través de la muestra de material; seleccionar un valor para un retardo entre muestras consecutivas L; seleccionar un valor para una dimensión embebida E; reconstruir un espacio de fases de la señal x(n); calcular una matriz de representaciones recurrentes; calcular el grado de determinismo; y determinar la presencia de daños en el material para un valor de DET inferior a 1.
