In the present work, a new fretting wear model taking account of the dynamic evolution of the debris layer is proposed to predict the wear profile under gross sliding conditions. The dynamic evolution of the debris layer is described by an exponential function of the debris thickness. A multi‐linear kinematic hardening model is employed to describe the cyclic plastic deformation of Ti‐6Al‐4V. The...
In the underlying study, a computational method to predict the cyclic plastic deformation and the fatigue life of medical PEEK is proposed. The OHNO‐WANG plasticity model was implemented as an Abaqus® user subroutine. The SMITH‐WATSON‐TOPPER criterion was implemented as a postprocessing Python script to predict the fatigue failure of PEEK. The validation of the OHNO‐WANG model with the five effective...
Metallic materials of railway disc brakes exhibit viscoplastic deformation behaviour under cyclic thermomechanical loadings. In this study, a viscoplastic Chaboche model is applied to describe the inelastic deformation behaviour in the braking process incorporating the inhomogeneous variation of temperature. The rate‐dependent hardening behaviour of 28CrMoV5‐8 steel is modelled by employing combined...
Resilient wheels are well‐known for their contribution to prevent squealing, impact noise and dynamic stresses on unsprung masses. In this study, a FE model is established in ABAQUS to analyze the stiffness of resilient wheels based on the Mooney‐Rivlin hyperelastic material theory. The modes of each part in the resilient wheel and the whole wheel are calculated. The static and dynamic stiffness of...
