•The isogeometric shell analysis framework is applied to deep drawn components.•A B-spline model is generated starting from laser scan measurements.•The model is used directly for the simulation of their dynamic behaviour.•The numerical results are validated with experiments. In this work, the framework of isogeometric shell analysis is applied to the simulation of the dynamic behaviour of thin components measured by a 3D laser scanner. To this end, a B-spline surface is reconstructed to describe the mid-surface of the components and is used for the analysis. The exact thickness distribution is also described through the B-spline basis functions and is considered in the numerical integration. Two components manufactured through deep drawing are studied and the surface fitting procedure is adapted to their particular geometry. The results are finally validated through experimental testing of these components.
