... is transformed into hydrodynamic lubrication, leading to a decline in the frictional coefficient. Furthermore, the vibration of UHMWPE, which is distinct from the frictional coefficient, intensifies with an increase in elastic deformation. Under high speed and heavy load, the vibrational accelerations...

.... They are colliding velocity, constraints of a human body by a hand support, facing direction of a human body and frictional coefficient between human body and seat surface or between human body and floor. The conditions for the numerical simulation are summarized in Table 4. Three kinds of colliding velocity 1,2...

... for the traditional strip-line footing when the embedment approaches zero. Parametric studies demonstrate that the bearing capacity factors for pipeline foundations are significantly influenced by the pipeline embedment and the pipe-soil frictional coefficient. With the increase of pipeline embedment, the bearing...

... to reproduce the behavior of a bolt connection with an explicit FEM code. The calculated strain is compared with the measured value to show the validity of the numerical model. After the validation, the effects of friction coefficient and initial torque on the stress loosening are examined by the presented...
