Abstract: A solution for contact problem based on contact surface
geometry is presented. The method uses discrete analytical surfaces to
represent the surfaces between deformable and rigid bodies. The contact
constraints are employed with consideration of geometry characteristics
of the discrete analytical surfaces. Then, the constraints are
introduced into the general governing equations to solve the contact
problem directly. The present method does not increase the DOFs of the
contact problem but avoids the selection of Penalty numbers in Penalty
function method comparision with traditional Lagrange multiplier and
Penalty function method. It is illustrated through numerical example
that, the present work are proven to be valid and effecient.
Key words: Contact problem Analytical surface Contact constraints
