... Rolling bearings are widely applied in key machinery such as national defense and transportation, and their mechanical state directly affects the operation safety of mechanical systems. Since the worse working environment, rolling bearings wear faster. Therefore, the dynamic model closely related...

.... Dynamic model Porous media Finite element analysis Two phase Recent research in geomechanics is mainly focused on transient phenomena occurring in earthquakes and explosive loading. For all of these the coupling between the deformation of the geomaterials such as soils and rocks and the motion...
