On the choice of contact parameters for the forced response calculation of a bladed disk with under platform dampers

Underplatform dampers (UPDs) are still in use to reduce the vibration amplitude of turbine blades and to shift the position of resonant frequencies.The dynamics of blades with UPDs is nonlinear and the analysis is challenging from both the experimental and the numerical point of view.A key point in obtaining a predictive numerical tool is the choic
