The anti-plane motion of two half-planes, both are composed of gradient non-homogeneous media and the interface between them is unilateral interface with Coulomb friction, is investigated.

Expanding application of theory of plane motion of rigid body;

Exploitation and application of experimental platform in plane motion;

Deduction of instant center acceleration of rigid body in plane motion;

Coupled dynamics modeling and analysis for flexible beam with planar motion;

It was pointed out that the actual center-line and theoretic meshing line of the paired gears varied in the form of planar motion due to the system vibration,and the actual meshing line was curvilinear.

In this paper, a vehicle model with three degrees-of-freedom is explored to analyze the relationship between the planar motions and roll motion of a vehicle.

We extend the traditional method by replacing a low pair with a higher pair,and the use of the method can produce all possible structural types of a planar kinematic chain with multiple joints and higher pairs in accordance with the adjacent matrix of the kinematic chain of a planar link.

This paper presents an adjacency matrix method for identifying topological symmetry to planar kinematic chains with multiple joints.

This paper presented a classification method to planar kinematic chains with multiple joints and higher pairs based on structural characteristics.
