“…A report covering Phase I of the study was submitted as scheduled (Leonards and Roy, 1976). The finite element computer code, dubbed FINLIN, had some unique features the most important of which was the procedure for fitting actual soil test data with spline functions and calculating incremental values of E and y in terms of octahedral normal and shear stress levels.…”

“…The soil mass is searched for tensile stresses; and if they exist, steps 2 and 3 are repeated until the tensile stresses are negligibly small . Chang and Nair (1973) and Leonards and Roy (1976) employed this procedure to account for the no-tension behavior of geologic material.…”

SUMMARYA simple friction-contact interface element is introduced which simulates frictional slippage, separation, and re-bonding of two bodies initially mating at a common interface and subsequently deforming with an arbitrary static loading schedule. Constraint equations between initially mating node pairs and the general principle of virtual work are used to formulate the interface element for a finite element solution procedure. Some advantages of the interface element include; easy implementation into standard finite element programs, direct determination of interface forces without round-off problems, and the generality afforded by the virtual work formulation to include other non-conservative models in the system.The application of the interface element to an idealized buried culvert problem illustrates that the model behaves properly. A second application, for a long-span culvert installation with incremental soil loading, demonstrates the importance of modelling slippage at the culvert-soil interface in order to conform with experimental observations.
