“…The coefficient of friction µ first increases towards µ p and then decreases towards µ r (equations (5) and (6), hardening/softening response), while D(e) increases towards unity (equation (17)). Therefore equation (16) at ultimate state can be written: (18) and on the basis of equation (11) (Fig. 4) is close to the limit value µ r .…”

“…Formulations relate as well to the assumptions of a perfect plasticity as to those of an hardening material (inter alia: [14], [18] - [23]), permitting also the analysis of particular conditions such as cyclic loading and softening ([24] - [26]). Along with a new definition of the kinematic state variables, stresses are related to displacements, and the theoretical structure of these models remains identical to that of the majority of the elasto-plastic models suggested for the description of soil behaviour.…”

A new axisymmetric joint element model for semi-analytical finite element analysis of axisymmetric bodies subjected to non-axisymmetric loading is proposed. The new joint element model for axisymmetric interface has three degrees of freedom: normal, tangential and circumferential directions, and describes debonding (normal direction), and slip (tangential and circumferential direction) on the interface. The new joint element model was incorporated into a finite element program and test-case analyses were performed. The results indicate that the new joint element model is useful in the semi-analytical finite element analysis for deeper understanding of stress distributions on the axisymmetric interface.

“…(3) Elasto-plasticity models. Ghaboussi et al (1973) proposed one of theˆrst elasto-plasticity interface models using a cap yield surface. A series of elasto-plasticity interface models have been developed on the basis of various assumptions (e.g., Fisherman and Fisherman et al, 1991;Gens, 1990; Boulon, 1990;Navayogarajah et al, 1992).…”

This paper describes an elasto-plasticity damage model, termed the EPDI model, of the interface between a structure and gravelly soil. The formulations are derived on the basis of a new model framework, with test-basis concepts and assumptions, for a uniˆed description of monotonic and cyclic behavior of such an interface. The model parameters, with physical meaning, are easily determined from a group of cyclic shear tests and a conˆning compression test. The comparisons of model predictions with the results for a series of tests under varying loading conditions demonstrate that the EPDI model is eŠective in accurate description of monotonic and cyclic stress-strain relationship of the interface between a structure and gravelly soil with capturing new features, including: 1) shear stress-strain relationship and comprehensive volumetric strain response (e.g., partly dependent on shear strain); 2) volumetric strain response that is dependent on the shear direction; and 3) evolution of behavior of the interface associated with the evolution of physical state.
