The model is rate independent and re- Received in revised form presents coupling effects between normal and shear displacements. Contact effects are 17 March 2016 included through a segment-to-segment contact model which considers stick, micro-slip, Accepted 15 April 2016 slide and slap behaviors at every point within the contact interface. The model has six Available online 29 April 2016 parameters and three memory variables without the need for integration during response Keywords: computations. Behavior of the model is validated using the available mechanical joint Contact interface records in the literature and it is successfully employed for model identification and Fri
