Abstract

CATALDO, Edson  and  SAMPAIO, Rubens. A brief review and a new treatment for rigid bodies collision models. J. Braz. Soc. Mech. Sci. [online]. 2001, vol.23, n.1, pp. 63-78. ISSN 0100-7386.  http://dx.doi.org/10.1590/S0100-73862001000100006.

In general the motion of a body takes place in a confined environment and collision of the body with the containing wall is possible. In order to predict the dynamics of a body in this condition one must know what happens in a collision. Therefore, the problem is: if one knows the pre-collision dynamics of the body and the properties of the body and the wall one wants to predict the post-collision dynamics. This problem is quite old and it appeared in the literature in 1668. Up to 1984 it seemed that Newton's model was enough to solve the problem. But it was found that this was not the case and a renewed interest in the problem appeared. The aim of this paper is to treat the problem of plan collisions of rigid bodies, to classify the different models found in the literature and to present a new model that is a generalization of most of these models.
