In this article the subject of model updating using the inverse eigensensitivity method that uses only eigenvalues in the calculation is examined. The problem of creating an underdetermined set of equations is studied and ways of preventing it are ad

In this study, based on parametric excitation originating from airflow oscillation, a novel nonlinear aeroelastic energy harvester is proposed. In this respect, first, the governing equation of the system is derived and studied thoroughly to understa

Super-harmonic components in response to the harmonic excitation are sensitive indicators of damages such as breathing cracks in beams or kissing bonds in adhesive joints. In a model-based damage identification process using pattern recognition, thes

The efficient dynamic stress assessment of turbine blades is of prime importance in turbomachinery design. An accurate prediction of forced response level of shrouded blades requires a very detailed finite element model in addition to a nonlinear sol

Hysteretic behavior due to some nonlinear sources is a common phenomenon in many mechanical systems. One of the sources of this behavior in such systems is dry friction in bolted or riveted joints. The dynamic response of a randomly excited thin rect
