By mere changes of variables, it appears that a large class of interface problems, including cohesive interface problems, may be solved using Signorini, Coulomb and standard NSCD algorithms. Emphasis is put on contact between deformable bodies. Examples illustrating numerical simulation are given for fibre-reinforced materials and for buildings made of blocks.","PeriodicalId":20023,"journal":{"name":"Philosophical Transactions of the Royal Society of London.

The model consists of a system of nonlinear differential equations that considers the multiple collisions as well as frictional effects at the contacting end, and allows one to predict the rigid and elastic body motion after the impact. The mode functions are selected such that the method can be made computationally as simple as possible, without compromising accuracy. To describe the impact between the elastic bar and the rigid surface, the classical Hertzian contact theory and elasto-plastic indentation theory are used. Particular emphasis is placed on the geometry of the bar because the unit tangent vector and the unit normal vector have first-order discontinuities. Analytical and experimental results are compared to establish the accuracy of the model.","PeriodicalId":20023,"journal":{"name":"Philosophical Transactions of the Royal Society of London.

The correct penalty terms are devised to include loss of energy at impact, i.e. an arbitrary restitution coefficient eε [0, 1]. There is a certain freedom in the choice of the penalty term, which permits more convenient practical choices. The convergence of this approximation is proved. The result presented here is much more general than the results already known: beyond generalized coordinates, it includes a smooth time-dependent set of constraints and the possibility of zero restitution coefficients.","PeriodicalId":20023,"journal":{"name":"Philosophical Transactions of the Royal Society of London.

The time-stepping methods already incorporate Coulomb friction, and are able to handle situations such as PainlevÉ's famous problem where impulsive forces occur without a collision. The elastic modes of vibration can be incorporated directly into the continuous formulation, but due to the stiffness typical of elastic vibrations, the numerical methods used need to be modified to incorporate them directly. The resulting numerical methods are dissipative in the limit, but only dissipate energy while there is contact.","PeriodicalId":20023,"journal":{"name":"Philosophical Transactions of the Royal Society of London.
