Paper Title:
Foam Reinforced Aircraft Fuselage Study
Abstract:
Fatigue cracking is a major symptom of aging aircraft skin that
could lead to widespread fatigue damage in the fuselage structure of the
aircraft. In this study the use of polyisocyanurate foam as a reinforcing
material to mitigate the stress distribution on the fuselage skin and its
effects on fatigue life is implemented through finite element approach.
The fracture parameters are obtained by conducting nonlinear finite
element (FE) analysis using commercial FE package ABAQUS. The numerical
results show that there is a significant
reduction in strain distribution in the fuselage and a three fold
increase in the fatigue of the fuselage when a 4" foam is added to
the fuselage skin.
