Numerical and experimental crashworthiness assessment of carbon-fiber reinforced thermoplastic energy absorbers
A numerical and experimental investigation is carried out in this study to evaluate the crashworthiness behavior, the energy-absorbing parameters, and the failure mode of thermoplastic composite energy absorbers under axial loading. The energy absorbers are thin-walled circular tubes made of woven polyphenylene sulfide carbon composite and have a bevel trigger on the top. Finite element analysis are conducted to predict the structural behavior of the tubes. To validate the numerical model, four specimens are manufactured and tested under an axial compression load. During the tests, the load and displacement are measured by a load cell, the evolution of the longitudinal strains is captured by digital image correlation, and the progression of the failure is recorded by a high speed camera. The tubes show a progressive failure mode, with delamination between the middle plies. A stable damage propagation is observed throughout the tests, where the bevel trigger plays an important role in increasing the stability and failure progression of the thin-walled tubes. The test results are compared to the numerical prediction, with good agreement for both crashworthiness parameters and delamination behavior. The thermoplastic composite energy absorbers achieved specific energy absorption values of up to 70 kJ/kg, indicating an adequate crashworthiness performance.

Comparación de la seguridad al deslizamiento de seis presas españolas. Criterios de diseño empleados frente al estado del arte actual.
Se ha desarrollado y aplicado un método simplificado para reevaluar de forma más precisa la seguridad al deslizamiento en seis presas de gravedad y contrafuertes en base a los resultados de modelos lineales numéricos, verificando su validez mediante análisis no lineales y medidas experimentales. Se han llevado a cabo sondeos con recuperación de testigo cercanos al tacón aguas arriba para inspeccionar posibles agrietamientos en las interfases hormigón-roca y se han instrumentado con extensómetros para analizar los datos de aperturas. Los resultados obtenidos, demuestran que los criterios de diseño utilizados en los años 50, en algunos casos no cubren el margen de incertidumbre esperado, respaldando así la necesidad de revisar las grandes presas españolas actualizando los análisis tal como rezan las Normas Técnicas de Seguridad de Presas que recientemente ha aprobado el Gobierno.

Revelación divina y cultura contemporánea
Hoy en día la teología se ha visto en la necesidad, debido al contexto de la cultura contemporánea en la que estamos inmersos, de dejarse como tarea para comprender el contenido de la fe y, a partir de ello, demostrar la gran importancia que se le debe dar a la revelación. Al ser Pannenberg uno de los grandes autores del siglo XX que desarrolla este tema, el presente libro tiene como objetivo ahondar en el pensamiento de dicho autor para plasmar la problemática y demostrar la gran relevancia que tiene la revelación como proyecto teológico en la situación actual.
