Descrizione Turbine blades are slender bodies that undergo large vibration amplitude in service and their dynamic behvior must be assessed in the design phase to prevent in service failures. In this project, the blade will be modelled as a beam and the effect of both geometric and contact nonlinearities on its vibration amplitude will be investigated, with special attention to the effect of beam and contact parameters. Time domain analysis will be performed. The benefits of model order reduction, implementing techniques already available in ANSYS will also be assessed. In addition, nonlinear based model order reduction techniques could also be implemented using PyMechanical which is a Pythonic interface with ANSYS Mechanical.
