      abstract     = {Seals are extremely useful devices to prevent fluid
                      leakage. However, the exact mechanism of roughness induced
                      leakage is not well understood. We present a theory of the
                      leak-rate of seals, which is based on percolation theory and
                      a recently developed contact mechanics theory. We study both
                      static and dynamic seals. We present molecular dynamics
                      results which show that when two elastic solids with
                      randomly rough surfaces are squeezed together, as a function
                      of increasing magnification or decreasing squeezing
                      pressure, a non-contact channel will percolate when the
                      (relative) projected contact area, A/A(0), is of the order
                      0.4, in accordance with percolation theory. We suggest a
                      simple experiment which can be used to test the theory.},
