摘要
We study the time-dependent contact area as a viscoelastic solid is squeezed against a randomly rough substrate. Using a recently developed contact mechanics theory we study how the contact area depends on time and on the magnification ζ. Numerical results are presented for self-affine fractal surfaces, and applications to tack, rubber friction, and sealing are given.
