摘要:We present an approach to construct NURBS (Non-Uniform Rational B-Splines) surfaces for tubular engineering structures. Isogeometric shell analysis using degenerated NURBS elements for tubular structures is also presented. We developed an automatic and simple algorithm to reconstruct multiple continuous NURBS surfaces using the skeleton withdrawn from the trimmed CAD model. Isogeometric shell analysis based on Reissner-Mindlin theory was applied to the reconstructed model. To verify the efficiency of the present method, we constructed the CAD model of the car body of an electric car and simulate the deformation of an electric car using isogeometric shell analysis.
