    Dynamic performance of a novel tuned vibration absorber with nonlinear friction interfaces

    A novel tuned vibration absorber with frictional interfaces (FTVA) is proposed in this study, combining the benefits of a tuned absorber and nonlinear dry friction dam** to dissipate energy. Firstly, the mec...

    Stress recovery algorithm for reduced order models of mechanical systems in nonlinear dynamic operative conditions

    Nonlinear forced response analyses of mechanical systems in the presence of contact interfaces are usually performed in built-in numerical codes on reduced order models (ROM). Most of the cases these derive fr...

    Numerical assessment of friction dam** at turbine blade root joints by simultaneous calculation of the static and dynamic contact loads

    In turbomachinery, the perfect detuning of turbine blades in order to avoid high cycle fatigue damage due to resonant vibration is often unfeasible due to the high modal density of bladed disks.
