... for vibro-impact as well as dry friction. This paper employs an isola detection procedure that was shown to give accurate results on such highly nonlinear applications. Several types of harmonic forcing are applied to the blade in order to observe subharmonic (i.e., with a fundamental frequency expressed...

... strategies with the reference time marching approach. An in-depth comparison is made with an emphasis on nonlinear frequency response curves (NFRC) and time signals. Finally, a physical analysis of the encountered isolas is presented through an in-depth investigation of the main modal contributions for each...
