Numerical and experimental study on dynamics of the planar mechanical system considering two revolute clearance joints

open access: yesInternational Journal of Mechanical System Dynamics, 2021
Due to assembly, wear and manufacturing errors and clearance in the joints are inevitable. When the clearance is introduced into a mechanical system, the impact force in the clearance joint will cause undesirable vibration of the system.

Recovering Missing Component Dependence for System Reliability Prediction via Synergy between Physics and Data [PDF]

open access: yes, 2021
Predicting system reliability is often a core task in systems design. System reliability depends on component reliability and dependence of components. Component reliability can be predicted with a physics-based approach if the associated physical models
