“…A purely discrete version of Chebyshev nets has been used in computer aided design to model the forming of woven reinforced composite materials to surfaces. However, many studies focus only on simple geometries such as a hemisphere [Robertson et al 1981;Ye and Daghyani 1997], polyhedral and rounded cones [Robertson et al 2000;Baillargeon and Vu-Khanh 2001] or translated sine curves [Wang et al 1999].…”

Figure 1: Wire mesh design allows creating physical realizations (1 st and 5 th images) of a given design surface (2 nd and 4 th images) composed of interwoven material (middle image) in an interactive, optimization-supported design process. Both the torso and the Igea face are constructed from a single sheet of regular wire mesh. AbstractWe present a computational approach for designing wire meshes, i.e., freeform surfaces composed of woven wires arranged in a regular grid. To facilitate shape exploration, we map material properties of wire meshes to the geometric model of Chebyshev nets. This abstraction is exploited to build an efficient optimization scheme. While the theory of Chebyshev nets suggests a highly constrained design space, we show that allowing controlled deviations from the underlying surface provides a rich shape space for design exploration. Our algorithm balances globally coupled material constraints with aesthetic and geometric design objectives that can be specified by the user in an interactive design session. In addition to sculptural art, wire meshes represent an innovative medium for industrial applications including composite materials and architectural façades. We demonstrate the effectiveness of our approach using a variety of digital and physical prototypes with a level of shape complexity unobtainable using previous methods.

“…This is then bagged and placed in an autoclave for curing and consolidation. Using this technology small to medium sized composite component can be made in one single forming operation, which has the potential to shorten part production times dramatically [30]. But it is more likely that there will be part failures through wrinkling caused by interplay shear issues [30].…”

“…The advantages of Composite Modeler were the seamless integration into ABAQUS/CAE, the parametrization with Python and the short calculation time due to the kinematic draping code based on the pinjointed net algorithm [20,21]. The outputs from this model were the fiber angle distribution and an unfolded outline of the draped ply, the so-called flat pattern.…”

A case study for the cost optimization of aircraft structures based on the operating cost as objective function is presented. The proposed optimization framework contains modules for estimation of the weight, manufacturing cost, non-destructive inspection cost and structural performance, the latter enhanced by a kinematic draping model which allows the fiber angles to be simulated more realistically. The case study includes five material systems:
