The expressions of the stress component in the plane(contacting body) are derived as the frictionally slipping contact arises between a plane and a cylinder on the basis of Hertz theory.

According to the particularity of friction&wear behaviors of electro-contact lead materials, to provide reliable experimental&theoretical basis for general adoption of market principle of new-type electro-contact lead materials by continuously directional solidification technology, a new-style electro-contact sliding friction&wear testing machine has been successfully developped.

A study on the vibration characters and fault diagnosis of plain bearing contact friction fault with the dead load;

The application of contact friction in bolt connection;

Research on shrinkage stress of concrete slabs with contact friction;

The contact characteristics between two bodies with sharply different stiffnesses were analyzed using a 3 D friction contact element method developed from a 2 D version to analyze nonlinear material changes.
