摘要

The absolute nodal coordinate formulation (ANCF) is a finite element procedure that has been developed specifically for the dynamic analysis of large deformation problems. This study concerns compatibility problems in thin rectangular ANCF shell elements, which have been reported in a recent study revealing that these elements lead to a loss of inter-element connectivity when used to discretize non-rectangular structures. This study presents an easily implementable extension to the already used formulae that reduces the inter-element connectivity problems significantly. The new approach is based on using a set of element specific parameters that corresponds to the initial shape of the element. The ability of both the standard and the proposed methods to express curved structures are compared as well as their respective numerical performance.
