          Abstract

          Resumen Este artículo estudia los diferentes modelos de crecimiento de grietas por fatiga, exponiendo una breve descripción histórica. Siguiendo la línea cronológica en el desarrollo de la investigación, hace especial énfasis en la ley de Paris y luego estudia algunos modelos específicos que, en general, corresponden a investigaciones de punta realizadas por diversos grupos, en el ámbito internacional. El objetivo principal es analizar y discutir las ventajas y desventajas de los diferentes modelos, teniendo en cuenta condiciones como la facilidad de aplicación, la disponibilidad de datos y la validez con respecto a los resultados experimentales.

          Abstract In this work, different models of fatigue crack growth are studied; a brief historical description on this subject is also provided. The research on this topic is described chronologically; however, emphasis is made on the model proposed by Paris. Then, a number of models that, in general, correspond to cutting-edge research conducted by various international research groups are studied. The main aim of this work is to analyze and discuss the advantages and disadvantages of the different models, taking into account criteria such as ease of application, data availability, and correlation with experimental results.
