Impactos de alta velocidad en materiales compuestos

Impactos de alta velocidad en materiales compuestos

Abstract

En el presente proyecto fin de carrera se ha estudiado el comportamiento de un elemento estructural fabricado con un determinado material compuesto ante el impacto de un proyectil a altas velocidades. Con este objetivo, se realiza un análisis desde el punto de vista numérico completando todas las simulaciones necesarias para extraer las pertinentes conclusiones. Para la realización de este estudio numérico, se ha optado por escoger una placa como elemento estructural fabricada con el material compuesto motivo de estudio de este proyecto. Para garantizar la máxima precisión en los ensayos numéricos que se van a realizar, se decide también incluir un elemento cohesivo en la placa. Para comprobar la validez del modelo escogido, se comparan los resultados numéricos obtenidos, con los resultados experimentales proporcionados. Se evalúan algunos de los parámetros más significativos del proceso de impacto, a saber: límite balístico del material, velocidad residual, energía absorbida por el compuesto y extensión del área dañada. Se hacen diversas simulaciones tanto para un amplio rango de velocidades de impacto. Tras la obtención de todos los datos, se realizan las gráficas pertinentes y se comparan los resultados numéricos con los experimentales. Finalmente, se extraen las conclusiones más relevantes y se concluye o no la validez del modelo empleado en este proyecto.
