Laws for normal and tangential contact including friction are developed
on the basis of a statistical surface model.
Standard FE techniques natu-
rally lead to a penalty type formulation.
Calculations with physical surface
parameters are in good agreement with analytical solutions.
amples including the dynamic problem of a bouncer moving between two
plates undergoing large rotations lead to reliable results as well.
Rough surfaces have contact only at their asperities.
The true area of contact
is much smaller than the apparent contact area resulting in very high local
Therefore early investigations assumed a plastic contact
of the asperities.
