Simulation of the contact bend of complex form slabs

Contact interaction of plates of a complicated shape resting on an elastic base of a 3D continuum type is considered. The plate's stressed-strained state is studied by the finite element method, and its contact interaction with the elastic half-space in analyzed by using boundary (contact) elements. During finite element solution of the problem of the plate's contact bending, the reaction pressure in the knots of a triangular mesh is determined by dual partitioning the contact domain into Dirichlet–Voronoi polygonal cells. The numerical examples considered illustrate the efficiency of the procedure developed for investigating the contact bending of the plates of the complicated shape.
