Abstract
La finalidad de este Trabajo de Fin de Grado es analizar el comportamiento de una tibia humana por el método de elementos finitos en diferentes estados de carga que se dan en la actividad diaria. En concreto, se ha decidido ensayar el ciclo de marcha humana normal y el ciclo de marcha humana con pasos cruzados para observar las diferencias que existen entre ambos tipos de marcha y posteriormente estudiar la resistencia de la misma aplicando criterios de fractura.
El trabajo presenta un apartado donde se realiza una introducción teórica sobre las características de los huesos humanos, sus propiedades, criterios de fractura y una explicación de los estados de carga que se van a estudiar.
El siguiente apartado hace una breve explicación al método de elementos finitos y una explicación del programa utilizado para obtener los valores: ABAQUS/CAE.
Por último se muestran los resultados alcanzados, las conclusiones tras analizarlos y posibles desarrollos futuros para mejorar y ampliar conocimientos respecto a este estudio.
The purpose of this Final Project Work is to analyze the behavior of a human tibia by the finite element method in different charge states that occur in daily activity. Specifically, it was decided to test the normal human gait cycle and the cycle of human walking with folded to observe the differences between both types of motion and then study the resistance of the same criteria applying fracture steps. The paper presents a section where a theoretical introduction on the characteristics of human bones, their properties, fracture criteria and an explanation of the charge states that will be studied is made. The next section gives a brief explanation of the finite element method and an explanation of the program used to obtain the values: ABAQUS / CAE. Finally the results achieved are shown, after analyzing the conclusions and possible future developments to improve and expand knowledge regarding this study.
