Simulation of Flexible Structures
Project DescriptionUsing the concept of deployable structures, and in particular inflatable space antennae, as a background target area, a few basic areas of computational structural modelling are studied. The specific objective for the space structures is to create minimum weight, minimum volume solutions for transport into and deployment to operational form in space. The simulation of these structures demand several computational analyses of dynamic and instability behaviour. The main work in the proposed project is the development of computationally accurate and efficient elements, primarily for thin membranes, using theories for large rigid deflections, and small but finite elastic deformations. Also, the control mechanisms for the deployment, are of major computational interest. The project parts will, together with previous and ongoing work in the group, give basic simulation tools, presently not available in commerical software, and an improved phenomenological understanding of the mechanical behaviour of these structures. Although primarily aiming at space structures, the studies are also highly relevant for many other types of optimized structures, including robotics, and the mechanical studies of biological tissues, but also for medi-technical small-scale applications.
