Nurbs-based free-form deformations
Web1 nov. 2009 · A NURBS-based CAD program is used to model shell structures built up from NURBS and isogeometric analysis is performed on the same model without meshing. … Web13 apr. 2024 · In this section, firstly, a stable data-driven structural analysis (DDSA) algorithm for three-dimensional continuum structures under finite deformation is proposed. Then the effectiveness of DDSA algorithm is verified by a numerical example. Finally, the solution techniques of the corresponding DDTO framework are given.
