A smooth C~1 interpolation for two-dimensional contact problems using parametriccurve technique was developed and implemented.The parametric curve can ensure C~1 continuityof the contact surfaces and provide a unique surface normal vector.Some numerical exampleswere used to illustrate the advantages of the newly developed representation of contact surface.The results reveal a significant improvement in the prediction of contact stresses and contactarea.The predicted contact stresses are less sensitive to the mismatch in meshes of the differentcontacting bodies.
