Predicting the coefficient of restitution of impacting elastic-perfectly plastic spheres
The current work presents a different methodology for modeling the impact between elastoplastic spheres. Recent finite element results modeling the static deformation of an elasto-plastic sphere are used in conjunction with equations for the variation of kinetic energy to obtain predictions for the coefficient of restitution. A model is also needed to predict the residual deformation of the sph...
متن کاملCovering Spheres with Spheres
Given a sphere of radius r > 1 in the n-dimensional Euclidean space, we study the coverings of this sphere with unit spheres. Our goal is to design a covering of the lowest covering density, which defines the average number of unit spheres covering a point in a bigger sphere. For growing n, we obtain the covering density of (n lnn)/2. This new upper bound is half the order n lnn established in ...
متن کاملMEAN VALUE INTERPOLATION ON SPHERES
In this paper we consider multivariate Lagrange mean-value interpolation problem, where interpolation parameters are integrals over spheres. We have concentric spheres. Indeed, we consider the problem in three variables when it is not correct.
متن کاملHermitian metric on quantum spheres
The paper deal with non-commutative geometry. The notion of quantumspheres was introduced by podles. Here we define the quantum hermitianmetric on the quantum spaces and find it for the quantum spheres.
متن کاملPlastic Spheres for Implantation into Tenon's Capsule in the Frost-lang Type Operation for Enucleation of the Eyeball.
FOR many years I have used perforated solid glass necklace beads of various sizes for the above purpose. They -were perhaps not so suitable as carbonized bone or gold basket spheres but were much easier to obtain than the former and far cheaper than the latter. Most of the other materials used for implantation have greater or lesser disadvantages; e.g., hollow glass spheres -may burst, smooth u...
