They are not renewable materials and their production, especially of carbon fibers, is energy-intensive.…”

Elastic kinetic structures are a recent approach to design transformable structures. Their transformation is based on elastic bending, that is compliant component behavior of structural members. This principle can be used to realize transformable structures with a stable deployment process. Regardless of a stable transformation, elastic kinetic structures are prone to static and dynamic loads due to their lightweight design. However, most of current research on these structures solely focuses on the principles of transformation. This paper proposes a concept for an active hybrid roof structure with a transformation based on elastic kinetics and rigid-body motion. The concept exhibits a stable structural deployment and active control components to counteract static and dynamic disturbances. Furthermore, this paper includes the realization and experimental evaluation of a mid-scale prototype structure.

“…En lo que respecta a la definición del término «violencia», resulta conveniente partir del reconocimiento de que, al igual que la mayor parte de los aspectos que estudiamos, se trata de un término «cargado» social y culturalmente, por lo que su significación variará en gran medida en función del ámbito cronológico y espacial en el que nos coloquemos en cada momento (Brockliss y Montgomery, 2010: 2). Dado que nosotros hemos decidido situar nuestra perspectiva desde el presente, adoptaremos aquí la posición de la Organización Mundial de la Salud, que 7 Vid, por ejemplo, Wiedemann (1989), Laes (2011: 22-28).

La Violencia en la Historia

La violencia ha sido considerada uno de los grandes ejes que explican el devenir de la humanidad desde los comienzos de la ciencia historiográfica. Nos repele y nos atrae, deseamos olvidarla pero no debemos dejar que caiga en el olvido, aparenta estar ligada a momentos históricos concretos pero atraviesa nuestro día a día… Quizás por estas razones la violencia, en todas sus posibles manifestaciones, lejos de ser un tema obsoleto, continúa teniendo un gran potencial como cuestión historiográfica, tal y como muestran las investigaciones que conforman este libro. De la mano de diferentes especialistas, y en un recorrido que va desde la Prehistoria hasta la Edad Contemporánea, este volumen colectivo analiza las violencias históricas desde la antropología física, la historia militar, la iconografía, o la historia de la infancia entre otros puntos de vista. Guerras, conflictos políticos y religiosos y sus significados simbólicos, o la violencia como espectáculo son algunas de las cuestiones que abordan sus páginas. Si bien existen pocos temas que hayan sido más estudiados por la historiografía que la violencia, este libro, fruto del Congreso Internacional La Violencia en la Historia, celebrado en la Universidad de Salamanca en octubre de 2019, es una muestra de que las preguntas históricas nunca se agotan y de que las violencias pasadas deben seguir siendo revisitadas desde nuevos enfoques.

“…Lightweight design is characterized by the utilization of materials with a favorable relation between density, strength and stiffness and by structural optimization of the component shape [1,2]. Branched structures are known to greatly improve the buckling stability and stiffness and thus offering the possibility to reduce weight [3].…”

The effect of laser annealing on the mechanical properties of severely deformed low alloy steel is discussed. Two different sets of annealing parameters were used to achieve improvements in formability. The resulting microstructures, tensile properties and hardness distributions are reviewed. Annealing at temperatures around 700 °C with very high heating and cooling rates leads to recrystallization at the surface and moderate grain growth in subsequent layers. The improvement in ductility is proven to be sufficient to prevent cracking during bending operations.
