Abstract: This article investigates the emergence of isolated branches of solutions for blade-tip/casing structural contact configurations by means of a numerical procedure relying on Melnikov's energy principle. This study is carried ...

Abstract: The study presented in this paper focuses on the analysis of rubbing interactions—including unilateral contact and dry friction—between a rotating fan blade and a rigid casing by frequency domain methods. Two previously ...

Abstract: This article introduces a numerical procedure dedicated to the identification of isolated branches of solutions for nonlinear mechanical systems. Here, it is applied to a fan blade subject to rubbing interactions and ...
