Resumen
[ES] La fatiga es el proceso de cambio estructural permanente que ocurre en un material cuando es sometido a una carga fluctuante a lo largo del tiempo produciendo la iniciación y propagación de una o varias grietas hasta la rotura de la pieza. En este Trabajo Fin de Grado se estudia la fatiga en viga rotatoria con tres tipos de probetas de acero normalizadas mediante un software de simulación basado en el cálculo de elementos finitos. Después, se va a comparar estos resultados con los calculados de forma teórica mediante diferentes métodos analíticos y con los obtenidos de forma experimental por un alumno en su Trabajo Fin de Grado, con el fin de evaluar la fiabilidad del programa para prevenir y evitar la falla por fatiga.
[EN] Fatigue is the process of permanent structural change that occurs in a material when it is subjected to a fluctuating load over time causing the initiation and propagation of one or more cracks until the parts breaks. In this Final Grade Project the fatigue of rotatory beams is studied for three types of standardized steel test pieces using a simulation software based on the finite element method. Then, these results will be compared with those calculated theoretically by different analytical methods and with those obtained experimentally by a student in his Final Grade Work, in order to evaluate the reliability of the program to prevent and avoid fatigue failure.
