Uncertainty Quantification for Nonlinear Vibration of Supercritical Drive Shaft With a Dry Friction Damper

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The supercritical drive shaft is becoming increasingly popular in helicopter transmission system. Dry friction dampers are specially employed to ensure the supercritical shafts crossing the critical speed safely. Due to design tolerances, manufacturing errors and time‐varying factors, the parameters of the damper are inherently uncertain ...

A DEM Model for Assessing the Mechanical Effects of CO2 Alteration in a Carbonate Rock

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT CO2 injection in the subsurface is considered an option to improve oil and gas production and, more recently, to store CO2. Consequently, there is a need to better understand the interactions between CO2 and rock deposits. Among the primary deposit candidates are carbonate rocks.
