This study investigates the frictional sliding dynamics occurring at the interface between two bodies in contact by using the Maxwell-slip model at the microscopic scale. The elastic body is modeled as a set of independent mass-spring units that are pulled with a rigid driver moving at a constant speed on top. Coulomb friction law is assumed at the mass-spring level. Initial compressive loading is represented by the degree of Poisson's expansion and its effect on the frictional sliding behavior is examined by using a dynamic solution to the Maxwell-slip model. Both stick-slip behavior and steady state behavior is observed for decreasing compressive loading. Our results show that stick-slip behavior at the macroscopic scale is observed caused by crack-like slip propagation at the microscopic scale at higher compressive loads. Macroscopically diminishing stick-slip behavior is observed for higher initial compressive loading conditions as pulse-like slip propagation through the interface is observed. At the highest initial compressive loading condition, propagation of train of pulses through the interface at the microscopic scale is observed causing a steady sliding behavior at the macroscale.
