Abstract: Modern aircraft engine designs feature reduced clearances that may initiate structural contacts between rotating and static components. A numerical strategy dedicated to the simulation of such interactions is here enriched ...

Abstract: Abstract. An equality-based weighted residual (E-WR) formulation is proposed to analyze the periodic responses of continuous systems subject to discrete frictional occurrences. A cantilever beam with an attached friction ...

Abstract: This paper provides a tutorial and summary of the theory of circulant matrices and their application to the modeling and analysis of the free and forced vibration of mechanical structures with cyclic symmetry. Our presentation ...
