The use of composite materials aimed to reduce the weight of structural components represents one of the topics of main interest for the aeronautical fields due to the need of designing aircraft components with the minimum possible weight, without compromises on the structural performances. Fuselage includes many stress concentration regions, such as doors and windows. In the present work, the mechanical behaviour of a composite fuselage section is numerically studied, by means of the Abaqus/CAE finite elements code. The load case considered in the frame of simulations is the pressurization load case. The stress distribution near the cut-outs and the crack resulting from the high stress locations have been evaluated and the influence of cu-outs on the pressure and deformation distribution have been assessed.

Abstract
The use of composite materials aimed to reduce the weight of structural components represents one of the topics of main interest for the aeronautical fields due to the need of designing aircraft components with the minimum possible weight, without compromises on the structural performances. Fuselage includes many stress concentration regions, such as doors and windows. In the present work, the mechanical behaviour of a composite fuselage section is numerically studied, by means of the Abaqus/CAE finite elements code. The load case considered in the frame of simulations is the pressurization load case. The stress distribution near the cut-outs and the crack resulting from the high stress locations have been evaluated and the influence of cu-outs on the pressure and deformation distribution have been assessed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
