Abstract. This work analyses a conserving time integration scheme applied to impact dynamics of one or more points against a rigid surface. This rigid surface may represents the boundary of a rigid body or it could represent a rigid cavity inside a body, and it should be represented by an implicit function. The points may be material particles, vertex of a rigid polyhedra, or nodes from a finit...

The problem of the indentation of a rubberlike layer bonded to a rigid cylinder and indented by another rigid cylinder is analyzed. The rubberlike layer is assumed to be made of a homogeneous Mooncy-Rivlin material. The materially and geometrically nonlinear problem is solved by using the finite-element code developed by the author. Results computed and presented graphically include the pressur...

This paper presents a pattern recognition approach to identifying contact formations from force sensor signals. The approach is sensor-based and does not use geometric models of the workpieces. The design of a fuzzy classiier is described, where membership functions are generated automatically from training data. The technique is demonstrated using supervised learning. Test results are included...

In this paper it is shown that the change in the energy for a linearly viscoelastic body (with Kelvin–Voigt type viscosity) in frictionless contact with a rigid obstacle can be accounted for by viscous losses and the work done by external forces. Thus there is no change in the energy due to impacts, unlike the case of rigid-body dynamics. The result can be extended to a wide class of dynamic vi...
