Short summary
Surface topography is an important feature to evaluate the surface quality of components, as is the stress concentration caused by the random surface topography. This paper proposes a numerical analysis method to study surface stress concentration factor (SCF) and relative stress gradient (RSG) for notched round-bar specimens. The surface SCF and RSG increased with increasing surface roughness, and a linear function relationship of surface roughness with surface SCF and RSG was established.
