La estimación de parámetros de sistemas dinámicos se basa en inferir los parámetros del sistema a partir del conocimiento de un conjunto de entradas y salidas. En ingeniería civil, la principal aplicación es la actualización ...
PhD Thesis
Mechanical behaviour of structured joints in 3D printed composite components: experimental, analytical and numerical study
(2020-06-10)
Joining mechanisms become specially relevant in structures where multiple parts are involved, for instance in the automotive or the aerospace sectors. Hence, the efficiency of these connections, which generally correspond ...
PhD Thesis
A fully physically based explanation of the scale effect in composites
(2021-05-13)
The scale effect in composite materials is known as the delay in the appearance of damage in the weakest laminas of a laminate (typically laminas oriented at 90 degrees). The availability of ultra-thin plies, of up to 20 ...
PhD Thesis
Computational Fracture Mechanics for Reliability of Composites at the Micro and Macro Scales
(2020-07-13)
In recent years, an increasing use of composite materials in aerospace and aeronautical applications has taken place. Fibre reinforced composites materials (FRCs) present high specific strength and stiffness ratios, ...
