The constitutive behavior of mechanical joints is largely responsible for the energy dissipation and vibration damping in weapons systems. For reasons arising from the dramatically different length scales associated with those dissipative mechanisms and the length scales characteristic of the overall structure, this physics cannot be captured adequately through direct simulation of the contact mechanics within a structural dynamics analysis. The only practical method for accommodating the

This document discusses a road-map for developing such constitutive models. 3 Acknowledgment The author list includes only those people who have actually contributed text and figures to this road map. Many additional people have contributed to the plans described. These include people formally on the joints team -experimentalists, analysts, and model developers -as well as others who have a stake in the exploitation of these models. Some of those people also provided critical review of this document and helpful suggestions. Among those who should be recognized in particular are
