Abstract Fiber-reinforced polymer (FRP) is widely used in various engineering fields due to its several outstanding properties. In geotechnical engineering, the interactions between FRP and soil play an essential role. this paper, molecular dynamics (MD) simulation method has been performed study interfacial mechanical behavior of epoxy-quartz interface as a subsystem FRP-soil structure. Uniaxial traction on bulk epoxy was conducted verify accuracy model. The nanoindentation nanoscratching mechanisms were analyzed, considering effect loading rate, sliding velocity, indentation depth. Abrasion models have proposed based relationship forces displacements. Simulation results indicated that indenter force hardness substrate increased with rate during nanoindentation, depths could be expressed by power law. along three directions velocity or nanoscratching, distance following exponential function. numerical simulations demonstrated surface wear had shape groove fan-shaped distribution process.
