Many single layer and multilayer higher-order theories were recently proposed for the analysis of the three-dimensional stress field that usually occurs in composite laminates especially in critical areas such as free edges. In this paper a finite element analysis based on a multilayer theory is performed in order to predict the complicated pattern of the stress field around the hole of laminates under tension. The numerical results are compared with the ones obtained with other modelling approaches, including single layer higher-order theories. The analysis shows that multilayer-theory-based finite elements can be effectively used in the prediction of the stress response of composite structures in cases of practical interests.

Abstract
Many single layer and multilayer higher-order theories were recently proposed for the analysis of the three-dimensional stress field that usually occurs in composite laminates especially in critical areas such as free edges. In this paper a finite element analysis based on a multilayer theory is performed in order to predict the complicated pattern of the stress field around the hole of laminates under tension. The numerical results are compared with the ones obtained with other modelling approaches, including single layer higher-order theories. The analysis shows that multilayer-theory-based finite elements can be effectively used in the prediction of the stress response of composite structures in cases of practical interests.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
