Abstract: We distinguish between, and discuss the applicability of, two levels of rigidity in rigid-body collision modeling. For rigidity in the strong force-response sense, collisional contact deformations ...

Abstract: We present a geometric representation of the set of three-dimensional rigid-body collisional impulses that are reasonably permissible by the combination of non-negative post-collision separation ...

Abstract: The problem of magnetically induced eddy current flow in a thin cracked plate is posed and solved for a few special cases. The current density is singular at the tip of a nonconducting ...

Abstract: We report on two-dimensional collision experiments with nine thin Delrin disks with variable axisymmetric mass distributions. The disks floated on an air table, and collided at speeds of about ...
