A Couple Contact Loading at the Unilateral Contact of Beams

Authors: Osipenko M. A., Kasatkin A. A.

The contact problem for the structure consisting of two beams is considered. The beams have the different lengths and the different variable thicknesses. One end of the shorter beam is clamped coinciding with the hinge dend of the longer beam.The other ends of the beams are free. The given loading is applied to the longer beam. The beams undergo the weak joint bending with the unilateral (receding) contact. There is no friction between the beams.The bending of each beam is described by Bernoulli–Eulermodel.The contact problem is to find the contact loading, i.e.

The Contact Problems for the Elastic Foundation with the Functionally Graded Coatings of the Complicated Structure

Authors: Aizikovich S. M., Krenev L. I., Trubchik I. S.

The contact problemfor the impression of axisymmetrical indenter into a functional graded elastic half-space is considered. Analytical methods for solving this problem have been developed. It is assumed that the indenter has a parabolic shape and contact between the indenter and the coating is smooth. The used method make it possible to find the analytical asymptotically exact problem solution.
