In addition, the contacting problem of plates was analyzed in this paper by using the penalty method, the contacting force of plates was derived, and the new methods for searching crateria were proposed.

In order to solve the contact problem of different parts of the blank, a new algorithm for contacting judgment is proposed.

Non-Hertz contact problems are studied according to multi-level multi-integration,and are computed with program.

The contact element method and original stress method were used to analyze the elastic plastic contact problem of wheel/rail with measured surface micro roughness.
