| Abstract: |
| Some new examining viewpoints about the numerical modeling of interface behavior have been discussed on the base of overall reviewing the previous research work, which usually arises in soil\|structure interaction. According to the features of the interface behavior in soil\|structure interaction such as the failure usually happens in a relatively finite zone inside the soil, the thickness of which is generally influenced by the soil property and the surface roughness of the structure. Hence the concept of the soil\|structure interaction interface should be generalized and suggests that the interaction should be simulated by a thin thickness interface element, especially the constitutive behavior of the element. In this way the numerical modeling of the interface behavior has been ended up in the problem of nonlinear analysis of soil mechanics. The paper suggest that the study of the interface behavior simulation should be rationalize through the constitutive modeling of interface element. |
