Abstract
[Abstract]: The advantages of laminates in terms of the chemical properties and mechanical
properties/weight relationship have motivated several applications of fiber-reinforced plastic (FRP)
composites in naval constructions due to the reduction in structural weight. This weight advantage has
motivated multiple investigations dedicated to dissimilar material joints. We present a methodology
for the interlaminar stress calculations of a tubular hybrid joint between an FRP panel and a steel
panel through tubular reinforcements. The proposed formulas allow the estimation of the shear and
normal stresses on the adhesive, which are generated in the bonding angle of the tubular hybrid
joint. The stresses generated at the adhesive bonding ends influence on the adherent’s adjacent layer.
A failure criterion is shown to check the accomplishment of the resulting stresses in the adherent
laminate. Finally, the proposed formulas are validated using the finite element method and compared
with the obtained interlaminar stresses.
