Abstract


Aluminium alloy EN AW-5754 is of particular interest to designers in the field of smart building facades, being capable of kinematic and dynamic architectural adjustments depending on the excessive operating climatic conditions (temperature, brightness, air flow). The study aims to carry out a complex structural analysis of facade modules from the alloy EN AW-5754, manufactured by U bending technology. To facilitate the volumetric displacement of the material during plastic deformation, respectively to avoid specific structural defects, the facade modules are accurately perforated along the curved bending lines; the laser beam technology allows different customized slot patterns for this purpose. The results of the analysis highlight the influence of the slots on the surface quality of the modules in the bending areas.
