The semiempirical modified embedded atom method has been applied to calculate the surface stress on the low index surfaces of fcc metals Ni,Pd and Pt,and the results are in agreement with that of the first principle calculation.The surface stress on fcc(110) surface along the [110] direction is about twice as large as in the [001] direction;and this indicates that the anisotropy of the surface stress is a characteristic of (110) surface of fcc metals.In addition,the magnitudes of the surface stresses on Pd and Pt(100) surfaces have been predicted.
