Abstract:
In this thesis, dynamic modeling of the phenomenon of correlation between slap and slip in the frictional contact of metal dry surfaces has been targeted. The slap and slip correlation, this means that there are two surfaces in the event of a slip, the movement in a vertical direction perpendicular to the surface is created simultaneously. The displacements from slap and slip have a regular relationship and the curves of these two appear to each other in the form of a butterfly loop and is called lift-up. For modeling of lift-up phenomena, initially the slap and slip models presented by previous researchers have been investigated, then the models that studied slap and slip correlation have been investigated. A thorough review of the resources available in this thesis provides a mathematical model for slap and slip correlation at friction surfaces which is used to model the slip between the surfaces of the Maxwell modified model and to model the slap of the linear model. In the results obtained by this modeling method, results for references, qualitatively better able to produce displacement butterfly curves and frictional test results than the existing available model. In this thesis, Abaqus software was introduced as an innovation of call models, as the mathematical model studied in the Abaqus software application and the results obtained from numerical analysis confirmed. To validate the mathematical model presented with the test results of one of the sources, the mathematical model was validated.
