This paper focuses on two different modeling approaches for delaminated multilayer composite panels: The former, applied by Risø DTU, adopts 20-node orthotropic solid elements with 3 degrees of freedom (DOF) per node, and the latter, developed by the University of Genoa, adopts shell elements with 6 DOF per node. The results obtained from the two finite element modeling methods are compared with experimental results from testing flat composite panels with and without delaminations. The aim of this work is to eventually compare the finite element results with the experimental data in order to discuss pros and cons for the modeling methods and to provide suggestions for reliable prediction of consequences of delaminations in thick composite panels.

Abstract
This paper focuses on two different modeling approaches for delaminated multilayer composite panels: The former, applied by Risø DTU, adopts 20-node orthotropic solid elements with 3 degrees of freedom (DOF) per node, and the latter, developed by the University of Genoa, adopts shell elements with 6 DOF per node. The results obtained from the two finite element modeling methods are compared with experimental results from testing flat composite panels with and without delaminations. The aim of this work is to eventually compare the finite element results with the experimental data in order to discuss pros and cons for the modeling methods and to provide suggestions for reliable prediction of consequences of delaminations in thick composite panels.
