Thermal Effects on Pull-Off Force in the Johnson–Kendall–Roberts Model

Abstract In this study, we investigate the effects of thermal fluctuations on generalized Johnson–Kendall–Roberts (JKR) model. We show that distribution pull-off forces in model is similar to Bradley model, and also consistent with experiment result observed Wierez-Kien et al. (Nanotechnology 29(15):155704 2018). Increasing temperature leads a broadening distribution, while reduction force. Additionally, force, which separated into an athermal term thermal-induced term, measured by using spring velocity ranging over 5 orders magnitude. for compliant spring, force significantly enhanced increasing velocity, mainly attributed contribution barely sensitive changes velocity.
