A number of recent laboratory studies have allowed quantification of the stress, strain, and deformation behavior of granular media at interfaces with various materials under loading and are summarized herein. This has been accomplished using various polymer impregnation and image analysis techniques in conjunction with axisymmetric and conventional interface shear tests. Due to the complexity of many of these interface dependent systems, numerical methods such as finite elements and finite differences are now being implemented to model the system performance. In these models, interface elements that accurately reflect the physical behavior of interfaces must be utilized. Accordingly, the objective of this paper is to highlight the characteristics of the interface that have a first order effect on interface behavior as identified through experimentation in an effort to develop a framework from which a rigorous numerical interface element can be developed.
