title Programmable Bending - grain-informed simulation and design
source Kepczynska-Walczak, A, Bialkowski, S (eds.), Computing for a better tomorrow - Proceedings of the 36th eCAADe Conference - Volume 2, Lodz University of Technology, Lodz, Poland, 19-21 September 2018, pp. 309-316
summary The project investigates the potential of programmable bending - a strategy, which informs bending simulations of multilayered veneer elements with the data of its anisotropic grain structure. Project further examines the possibilities of using these irregular material characteristics as a design driver. The project questions the possibility of informing the design with the particular characteristics of the material structure and of creating complex geometries from non-customized or minimally customizes mass-produced elements. Project develops a workflow, in which a two-dimensional scan of the material is transformed into a vector field and consequently into a mesh with variable stiffness characteristics. The stiffness of each edge within a mesh was calculated basing on an angle between this edge and the relevant vector within a vector-field. That resulted in realistic simulation, which differentiated bending characteristics along the grain and perpendicular to the grain. Uneven connection of several layers of active-bended veneer allows to accumulate local stresses and pre-program bending characteristics of the structure. As a result active-bended structure forms particular predefined and predesigned shape and possesses locally variable stiffness and flexibility. The project applies this strategy to the design of the pavilion located within the urban context of a public space.
