The harmonic balance (HB) method is widely used in the literature for analyzing the periodic
solutions of nonlinear mechanical systems. The objective of this paper is to exploit the …

Turbine bladed disks or blisks, which constitute critical components of most modern
turbomachinery, are known for their complex vibratory behavior. The nonlinear dynamics …

The paper deals with the nonlinear stochastic dynamics concerning the detuning
optimization in presence of random mistuning of bladed-disks with geometrical …

The recently developed generalized Fourier–Galerkin method is complemented by a
numerical continuation with respect to the kinetic energy, which extends the framework to …

The concept of nonlinear modes has been proved useful to interpret a wide class of
nonlinear phenomena in mechanical systems such as energy dependent vibrations and …

Steady state dynamics of a horizontally supported Jeffcott rotor system under nonlinear
restoring forces has been studied in this work. Vibration reduction of the rotor system using …

This paper investigates a new passive damper coupling the energy dissipative mechanisms
of dry friction and piezoelectric shunting circuit for Integrally Bladed Disks (blisks). The idea …

In this work, we show that a recently proposed method for experimental nonlinear modal
analysis based on the extended periodic motion concept is well suited to extract modal …

A novel probabilistic approach for the design of mechanical structures with friction interfaces
is proposed. The objective function is defined as the probability that a specified performance …

Abstract Design of complex mechanical structures requires to predict nonlinearities that
affect the dynamic behavior considerably. However, finding the forced response of nonlinear …
