This paper presents a general geometric theory of in-plane motion of underplatform
dampers as a function of blade neck deflection and the resulting platform kinematics. In …

Friction interfaces are unavoidable components of large engineering assemblies since they
enable complex designs, ensure alignment, and enable the transfer of mechanical loads …

Complex high-value jointed structures such as aero-engines are carefully designed and
optimized to prevent failure and maximise their life. In the design process, physically-based …

In the bladed disks of turbomachinery, the problem arises of finding a damping device that
reduces as much as possible the amplitude of the alternating stresses produced by the …

The study of contact is an engineering pursuit that spans multiple disciplines and scales.
Structural dynamics, as well as aspects of nonlinear dynamics and vibrations, is concerned …
