title = "Analysis of industrial sheet metal forming processes using an enhanced rotation-free basic shell triangle",

abstract = "An enhanced rotation-free three node triangular shell element (termed EBST) is presented. The element formulation is based on a quadratic interpolation of the geometry in terms of the six nodes of a patch of four triangles associated to each triangular element. This allows to compute an assumed constant curvature field and an assumed linear membrane strain field which improves the in-plane behaviour of the element. A simple and economic version of the element using a single integration point is presented. The efficiency and accuracy of the EBST element using an explicit dynamic scheme are demonstrated in an example of application to a practical sheet metal stamping problem.",
