NURBS based form finding of efficient shapes for shells

Alic, Vedad LU and Persson, Kent LU (2016) In Proceedings of 29th Nordic Seminar on Computational Mechanics – NSCM29
Abstract
This paper presents ongoing research on using non-uniform rational b-splines
(NURBS) based isogeometric analysis for form finding of efficient shapes for shells. The form finding is made using dynamic relaxation together with NURBS based membrane elements. The method is employed directly to design geometry, without the need for any further discretization. The method is implemented in two plug-ins for Rhinoceros 3D and Grasshopper 3D. The method describes form found geometries well with very few elements and can be used to find efficient shapes very rapidly and directly in design software, and is thus suited for design explorations.
