Title:
Stress-adapted numerical form finding of pre-stressed surfaces by the updatedreference strategy 
Abstract:
In this paper we present the updated reference strategy for numerical formfinding of pre-stressed membranes, which is based on standard finite elementdiscretization. The singularities of the inverse problem are regularizedby a homotopy mapping. A projection scheme is proposed where anisotropicpre-stress is defined with respect to an additional reference plane, whichreflects the initially developable surface of membrane strips in the productionprocess. Physically problematic combinations of edge...    »
