A number of problems of dynamic deformation in the presence of moving contact surfaces is considered. A grid-characteristic method, using two-dimensional irregular triangular grid and a hybrid scheme with 1–2 order of approximation is adapted. An algorithm for calculating the force of friction and the force of static friction is proposed. A numerical solution to problems of the wheel rolling, of the generation of shear waves, of acceleration of a plunger in a tube, of ricochet is obtained.
Keywords: mechanics deformable rigid body, grid-characteristic method, irregular grid, dynamic contact, collision detection, seismic surveys, method of falling load.
Mots-clés : Delaunay triangulation, friction
