| Abstract Scope |
Bistable fully closed shells can serve as long supporting structures that can be folded into a compact transport geometry and unfolded at the construction place and can be produced by incremental die-bending. In order to find a suitable bending radii a semi-analytical model was developed and experimentally validated in previous research. Nevertheless, minor deviations have occurred in the prediction of the stable geometries curvatures and the degree to which other parameters influence the achievability of bistable shells is still unclear. Therefore, an enhancement of the existing model is described and used for an analysis of the influence of different parameters on bistability and final shell geometries. To verify the results, experiments with two different materials (AISI 1095 and AISI 301) and different bending radii are presented. Finally, the paper shows the influence on the residual stress distribution and based on this, production limits for bistable fully closed shells are derived. |
