Investigating the effect of rotational degree of freedom on a circular cylinder at low reynolds number in cross flow [PDF]
, 2011 Numerical simulations of Vortex-Induced Vibrations (VIV) of a circular cylinder in cross flow with a rotational degree of freedom about its axis have been carried out by means of a finite-volume method.

A compound double pendulum with friction
Forces in Mechanics, 2023 We study a version of the two-degree-of-freedom double pendulum in which the two point masses are replaced by rigid bodies of irregular shape and nonconservative forces are permitted.
