Algorithm 1 Contact pressure distribution

Initialize f(0), d(0), and p(0)

1   Calculation of wear depth (hij)n

2   Profile update f(n) = f(n−1) + (hij)n

3   Calculation of new indentation depth d(n)

4   Calculation of new contact pressure distribution p(n)

5   if |f(n+1) − f(n)| < tolerance go to step 6 else go to step 1

6   Limiting profile p(n) = const.
