Some considerations on a fournode finite element for composites with the drilling degrees of freedom
Abstract
A platetype finite element with six degrees of freedom (DOF) for each of the four nodes is introduced. To obtain this result a Mindlintype bendingplate element is superimposed on a three DOF per node planestress element. Composites are simulated using the YNS theory. A few considerations on some plateshell elements already tested are reported and the introduction of the drilling DOF is justified. A comparison with the results obtained by using a ninenode reducedintegration isoparametric element is also supplied.
