A time-domain substructure synthesis for finite rotations of flexible mechanical systems

MATEC Web of Conferences, 2018
This paper presents a floating IBS method for dynamic prediction of structures with finite rotations. The conventional IBS (impulse-based substructuring) method is efficient and accurate in structural transient impact analysis.

Simulation of Fretting Fatigue in Conformal and Concentrated Contacts

Tribology Online, 2011
Fretting fatigue is a possible failure mode of rolling bearings, as well as for other machine elements with contacts. For a rotating bearing it normally can occur in the interfaces between outer ring/housing, and inner ring/shaft.
