      abstract     = {When a body is exposed to external forces large local
                      stresses may occur at the surface because of surface
                      roughness. Surface stress concentration is important for
                      many application and in particular for fatigue due to
                      pulsating external forces. For randomly rough surfaces, I
                      calculate the probability distribution of surface stress in
                      response to a uniform external tensile stress with the
                      displacement vector field parallel to the rough surface. I
                      present numerical simulation results for the stress
                      distribution σ(x,y) and show that in a typical case the
                      maximum local tensile stress may be ∼10 times bigger than
                      the applied stress. I discuss the role of the stress
                      concentration on plastic deformation and surface crack
                      generation and propagation.},
