      abstract     = {Widely used to quantify material wear, the Archard wear law
                      was derived from the asperity flattening model. However, the
                      flattening model is so idealized that it cannot properly
                      represent the real situation with general interlocked
                      asperities, where asperity plowing dominates the wear
                      instead of shearing flattened asperity. Using molecular
                      dynamics simulations, we discussed if Archard law can hold
                      during plowing wear of interlocked interface. Our results
                      indicated Archard law breaks down when fracture dominates
                      the wear. Furthermore, increasing interfacial adhesion or
                      decreasing material ductility changes the dominant wear
                      factor from plasticity to fracture. Finally, we proposed a
                      criterion to determine when Archard wear law will break down
                      and discussed the proposed criterion for real materials.},
