Abstract
In the conventional adhesive contact mechanics, the value of the Tabor parameter μ provides criterion for the applicability of the JKR and the DMT models. While the JKR model is an appropriate approximation for a large Tabor parameter (μ > 5), Ciavarella et al. demonstrated that the JKR theory overestimates the hysteresis loss during an approach-retraction period, even though the Tabor parameter is high enough. The present study investigates how surface tension affects the hysteretic loss in an approach-retraction cycle of spherical adhesive contact. With surface tension, Wu’s solution is invalid in terms of the prediction of the jump-in position. Based on Civarella’s research, we developed a hybrid model to approximate the hysteretic loss. This model used direct numerical solution from the Lennard-Jones potential Law. The same method can also be generalized to the spherical contact system with finite stiffness, in terms of hysteretic loss determination.
