Title: Análisis experimental del comportamiento a flexión dinámica de vigas sándwich Author(s): Ivañez, Inés; Santiuste, Carlos; Sánchez-Sáez, Sonia Abstract: En este trabajo, se ha analizado experimentalmente el comportamiento a flexión dinámica de vigas sándwich con pieles de fibra de vidrio/poliéster y núcleo de espuma de PVC. Se han llevado a cabo ensayos dinámicos de flexión en tres puntos, de los que se ha obtenido la fuerza de contacto, la energía absorbida y el desplazamiento máximo de ambas pieles. Se ha analizado la influencia de la energía de impacto sobre estas variables y en el modo de fallo de las vigas, observando que la compresión del núcleo bajo el área de contacto provoca una localización del daño que favorece la rotura de la piel superior.

Title: Influence of temperature on composite aeronautical structural bolted joints Author(s): Santiuste, Carlos; Barbero, Enrique; Miguélez, Henar Abstract: This work focuses on the analysis of temperature and bolt torque influence on aeronautical joint behaviour. A numerical model based on finite elements was developed. Results obtained from numerical simulations showed coupled influence of temperature combined with torque level on the joint Description: 15th International Conference on Composite Structures (ICCS/15), University of Porto, Porto, Portugal, 15-17 June 2009

Title: Ballistic behavior of preloading CFRPs panels Author(s): García-Castillo, Shirley K.; Sánchez-Sáez, Sonia; Barbero, Enrique; Navarro, Carlos Abstract: In this paper the effect of static biaxial preloading of CFRPs plates under high velocity impact is investigated experimentally. Results are compared with those obtained when no static loads are applied to the specimens. Two magnitudes were measured from the tests: the residual velocity of the impacting projectile and the extension of the damage area in the laminate. Description: ICCE 12.
