Abstract Recent advancements in biomedical, transportation and energy sectors have resulted in high demands for advanced materials with superior resistance to creep deformations. In particular, understanding contact and friction creep are vital in numerous applications such as implants, high-temperature turbines/engines, advanced automobiles, and trains as well as microelectromechanical switches. Contact area and friction coefficient, especially in applications involving high local loading, are significantly affected by creep and time-dependent deformation leading to components durability and performance deterioration. This paper first briefly reviews elastic-plastic asperity-based contact models due to their importance and inherent connection to contact and friction creep models. A survey on experimental and numerical approaches to model, quantify, and characterize creep influence on contact and frictional properties of metals and polymers is then provided in detail. The current state-of-the-art models for creeping contacts and friction are reviewed for different material properties, loading conditions, and holding times. In addition, a brief review of different methods to extract surface creep parameters, especially at elevated temperatures, is provided.
